GDW2000 Installation Guide: 2000m2 Tri-Band Signal Booster Setup, Yagi Alignment, Cable Routing and Multi-Zone Testing for UK Enterprise, Warehouse, Hotel and Large Office Sites

GDW2000 Installation Guide: 2000m2 Tri-Band Signal Booster Setup, Yagi Alignment, Cable Routing and Multi-Zone Testing for UK Enterprise, Warehouse, Hotel and Large Office Sites

Installing the Boost4U GDW2000 across a 2000 m2 UK enterprise warehouse, hotel, large office block, distribution centre or showroom takes 30 to 60 minutes of ordinary DIY work: check the outdoor dBm reading on Band 8, Band 3 and Band 1, mount the 8 dBi Yagi 3 to 5 m high on a clear bearing to the serving mast, keep it at least 10 m vertically from the nearest indoor panel, route the 10 m outdoor and 5 m indoor coax to the BS and MS ports in the correct order, extend the outdoor run to 20, 30, 40 or 50 m where the 2000 m2 footprint demands it, power on after wiring, then walk every zone while the automatic gain control settles.

Answer first: the GDW2000 is a self-contained tri-band commercial repeater that a facilities manager, maintenance engineer or competent owner can install without a specialist RF contractor, even at the 2000 m2 rating and the 200 simultaneous-user headroom. The whole job breaks into ten factual stages: (1) confirm a usable outdoor signal on Band 8, Band 3 and Band 1; (2) choose a Yagi mounting point 3 to 5 m above roofline with a clear bearing to the serving mast; (3) keep the donor Yagi and every indoor panel at least 10 m apart vertically; (4) connect the 10 m outdoor coax to the BS port and the 5 m indoor coax to the MS port; (5) extend the outdoor run to 20, 30, 40 or 50 m only when the supplied length cannot reach across a 2000 m2 footprint; (6) place the amplifier chassis near the building core so panels reach every zone; (7) connect antennas before plugging in the AC adapter; (8) read the per-band LED indicators while the automatic gain control warms up; (9) test calls, 4G speed and 3G fallback zone by zone across the enterprise floor plan; and (10) add extra indoor panels only where one panel cannot reach a distant wing or floor. This guide explains each stage with the exact dBm ranges, heights, port labels, cable lengths and timings the GDW2000 needs for 2000 m2.

The GDW2000 is rated for up to 2000 m2 of indoor coverage and up to 200 simultaneous users, which places it in the enterprise warehouse, hotel, large office block, distribution centre, showroom and multi-wing commercial bracket rather than the small-flat bracket. It ships with an 8 dBi directional Yagi outdoor antenna, a 5 dBi panel or whip indoor antenna, a 10 m low-loss outdoor coaxial cable, a 5 m low-loss indoor coaxial cable with N-type connectors, and an AC 100 to 240 V 50/60 Hz adapter stepping down to DC 5 V with a UK 3-pin plug. It delivers at least 65 dB uplink gain and at least 70 dB downlink gain on each of Band 8, Band 3 and Band 1, with maximum output power of at least 27 dBm. It carries UKCA and CE certification and operates under Ofcom's licence-exempt rules, so no frequency licence and no annual fee are required.

Before you drill a single hole, treat the enterprise install as a measurement job, not a wiring job. Every common failure reported to Boost4U support on a 2000 m2 site is not an amplifier fault: it is a Yagi aimed at the wrong mast, a pair of antennas mounted too close together, a swapped BS and MS cable, an outdoor run left at 10 m when the building depth needs 30 or 40 m, or an outdoor signal that was never strong enough on one of the three bands. Working through the ten stages below in order avoids those mistakes, and the 30 to 60 minute estimate assumes you already own a screwdriver, a drill, a ladder and a phone in field-test mode; surveying across the full boundary of a large site happens before the clock starts.

Quick Answer: Can You Install the GDW2000 Yourself in 30 to 60 Minutes on a 2000 m2 Enterprise Site?

Yes. The GDW2000 is designed as a DIY licence-exempt repeater and the manufacturer quotes a 30 to 60 minute installation time for a single competent person, even at the 2000 m2 and 200-user rating, because wiring and mounting are the same physical steps as on a smaller unit; only the cable choice, panel layout and zone testing take longer on a large footprint. The numbered facts below set the baseline before you touch the kit.

  1. Outdoor signal must be present on all three bands. A usable 2G reading sits between -76 and -90 dBm, a usable 3G reading between -80 and -94 dBm, and a usable 4G reading between -97 and -105 dBm. Read each band separately in field-test mode; a strong 2G bar on its own tells you nothing about 4G.
  2. Mount the 8 dBi Yagi 3 to 5 m above roofline or chimney height. That height clears warehouse foliage, neighbouring roofs, steel roof sheets and concrete walls that scatter the 900, 1800 and 2100 MHz waves across a 2000 m2 footprint.
  3. Maintain at least 10 m of vertical separation between the outdoor Yagi and the nearest indoor panel. Less than that feeds the re-radiated signal back into the donor antenna and triggers oscillation protection on every band at once.
  4. Use the supplied 10 m outdoor cable and 5 m indoor cable as the starting point. Upgrade to 20, 30, 40 or 50 m low-loss outdoor cable only when the mast-facing mounting point cannot be reached with 10 m; at 2000 m2 this upgrade decision is the most common enterprise ordering error.
  5. Plug the outdoor antenna into the BS port and the indoor antenna into the MS port. BS means base station (donor) and MS means mobile station (server); swapping the two produces no signal and can confuse the AGC across all three bands.
  6. Place the amplifier chassis near the building core of the 2000 m2 footprint so panels reach the warehouse floor, hotel corridor, meeting rooms and loading bay without stretching the 5 m indoor lead past its useful length.
  7. Wire both antennas first, then power on. Connect all N-type plugs, check the BS and MS labels, and only then plug the AC 100 to 240 V adapter into a UK mains socket.
  8. Watch the LED indicators for 3 to 5 minutes while the automatic gain control locks onto the donor signal on each band. A steady green band light means gain settled; a flashing amber light means oscillation or weak donor.
  9. Test every zone, not just reception. Place a 2G voice call on O2 or Vodafone, run a 4G speed test on EE or Three, and check 3G fallback on Band 1, in the weakest corner of the 2000 m2 footprint.
  10. Expand with extra panels, not a second Yagi. Where one panel cannot reach a distant wing or floor, split the MS output with an N-type splitter; never split the BS donor side.

These ten points are the skeleton. The sections below expand each one into measurable steps, numbers and troubleshooting checks, and the comparison table later in this guide shows which optional upgrades are justified for a 2000 m2 enterprise building and which are marketing noise.

Step 0: Check the Outdoor Signal with dBm Readings Before Buying or Mounting

A repeater can only amplify what the donor antenna receives. If the Yagi position has no usable signal on a band, no amount of gain at >=65 dB uplink and >=70 dB downlink can manufacture that band out of nothing. The pre-install survey therefore happens before drilling, before ordering a cable upgrade, and before mounting the bracket. On a 2000 m2 enterprise site the survey matters even more because the building often sits on a main road at the front but backs onto open fields or a fenced yard at the rear, and the serving mast for each band can sit on a different side.

The three dBm ranges the GDW2000 expects at the Yagi

Walk the boundary of your property with the phone screen visible and read the received signal strength in field-test mode. The GDW2000 amplifies three independent services, so you must check three independent readings rather than trust the subjective bar count.

Service / Band Good outdoor range Weak but workable What it means on screen
2G GSM, Band 8 (900 MHz) -76 to -90 dBm -90 to -100 dBm O2/Vodafone voice calls and SMS; EE 2G fallback where still broadcast
3G UMTS, Band 1 (2100 MHz) -80 to -94 dBm -94 to -104 dBm All four networks' 3G data fallback; matters most in rural commercial spots
4G LTE, Band 3 (1800 MHz) -97 to -105 dBm -105 to -112 dBm EE and Three 4G data; shallowest range because LTE decodes at lower power

Interpret the numbers as a scale from strong to unusable

-76 dBm on 2G is a healthy, line-of-sight reading that the Yagi will turn into a loud indoor signal. -90 dBm on 2G is still comfortably workable and the amplifier adds >=70 dB of downlink gain with margin to spare. -94 dBm on 3G sits at the edge of the recommended band but still produces a stable data session once amplified. -105 dBm on 4G LTE is the practical floor: below roughly -110 dBm the LTE receiver loses the control channel and the phone falls back to 3G or shows no service. The GDW2000's higher >=70 dB downlink budget absorbs more wall, floor and steel loss across 2000 m2, but it cannot invent a donor band that the Yagi never receives.

How to read dBm rather than bars

Phone bars are subjective and differ between iPhone and Android; the dBm figure is the measurement the amplifier actually sees. On an iPhone, enter field-test mode from the dialler and watch the RSRP or RxLev value while standing still. On Android, use the engineering or network diagnostics menu under About Phone, or a free field-test app that lists serving-cell RSRP by band. Hold the phone away from your body, because a hand and head absorb 3 to 5 dB, and read the value on the road-facing side of the building rather than the rear yard if the mast sits on the road side.

Where to survey: front, rear, sides and roof across a large site

Stand at the front pavement, the rear fence, each side wall, the loading bay, the delivery yard, and the base of the chimney or proposed bracket position. Record all three readings at each spot. The strongest combined spot is where the Yagi goes. On many UK 2000 m2 buildings the front pavement reads well on Band 8 but the side elevation reads better on Band 1 because a different mast serves that direction; the Yagi must point at the mast carrying your weakest band, not the nearest mast on the map. For a high-street showroom the street-facing roof edge usually wins over the back yard, while a rural warehouse often reads best at the field-side gable.

Survey warning: if any of the three bands reads below its workable floor at every outdoor position on your land, the GDW2000 cannot manufacture that band. You may still improve the other two services, but the missing band stays missing. In that case choose a higher mounting pole or the optional high-gain Yagi before committing, and remember O2 and Vodafone 4G on Band 20 at 800 MHz are outside this unit's design entirely.

Choosing the Yagi Mounting Spot: Height 3 to 5 m and Line of Sight

The 8 dBi Yagi is directional: it collects signal from a narrow forward beam and rejects signal from the sides and rear. Its usefulness depends on two geometric choices, the mounting height and the azimuth bearing, and both are set during the survey rather than after drilling. On a 2000 m2 enterprise site the mounting point often decides whether you need a 10 m cable or a 40 m upgrade, so pick the bracket before you order cable length.

Mount 3 to 5 m above the roofline or chimney stack

The manufacturer recommends a mounting height of 3 to 5 m for the Yagi. At 3 m the antenna typically clears surrounding hedge lines, single-storey annexes, low rendered walls and parked commercial vehicles. At 5 m it clears two-storey neighbouring gables, mature tree canopies and steel roof ridges that scatter 2100 MHz most heavily, because higher frequencies lose more energy when foliage and metal cross the beam. A chimney bracket, fascia bracket, wall-mast or standalone pole all work; the deciding factor is whether the chosen point can hold the Yagi at that height with a rigid fixing and a clear downward cable entry.

Clear the beam path to the serving mast

A Yagi gains 8 dBi by focusing the forward beam, so anything inside that beam within 30 degrees to either side costs you gain. A 30-degree aim error itself costs 3 to 6 dB. Before drilling, trace the bearing from the survey app to the mast and confirm no tall tree, neighbouring chimney, gantry, solar panel array, sign tower or metal tank sits inside the first 50 m of that path. If it does, move the bracket horizontally along the same wall until the beam clears, even if that means a slightly longer cable run; a clearer beam with a longer cheap cable beats a blocked beam with a short one.

Weatherproofing and fixing on an enterprise roof

The Yagi supplied with the GDW2000 is weatherproof, but the N-type connector at the cable entry is not. Seal the connector with the supplied weather boot or self-amalgamating tape, angle the connector pointing down so rainwater runs away rather than into the plug, and tighten the U-bolts firmly without over-torquing the aluminium elements. The unit's operating temperature range of -10 C to +55 C means outdoor mounting through winter frost and summer sun is normal, but the connector seal is what protects that rating year after year, especially on a commercial roof exposed to standing water and repeated wind.

Antenna Separation: Why 10 m Vertical Distance Prevents Oscillation Across 2000 m2

The single most important geometric rule in this install is the minimum 10 m separation between the outdoor donor Yagi and the nearest indoor server panel. Oscillation, also called self-feedback, happens when the panel's re-radiated signal reaches the Yagi and the amplifier treats it as fresh donor signal, boosts it again, and feeds it round in an ever-rising loop until the stage overloads, distorts audio, wastes power and can raise the noise floor at the neighbour's cell. The GDW2000's >=27 dBm output and >=70 dB downlink gain make stable isolation more important, not less.

Why the rule is vertical and measured at 10 m

The GDW2000 spec sheet states a minimum antenna separation of 10 m, and the practical installation guidance treats it as a vertical distance where possible: mount the Yagi on the chimney or roof mast at roof height and the panel on an internal wall or ceiling in the building core on a lower floor, so the floor slab, stair void and internal walls sit between the two. Vertical separation through a concrete floor slab costs far more isolation than horizontal separation across an open-plan hall, which is why a multi-storey office block naturally meets the rule while a single-storey open warehouse of 2000 m2 on one plane can struggle to.

What happens if separation is short

Below 10 m the per-band AGC can no longer hold the loop stable. The symptom is a flashing amber oscillation LED on the affected band, a hot amplifier chassis, muffled call audio, or a 4G speed that rises for a minute then collapses as the stage backs off. The fix is physical, not electronic: raise the Yagi, move the panel deeper into the building, or add an intervening solid wall. Software or gain dials cannot compensate for antennas radiating into each other, and the GDW2000 has no manual gain dial to crank anyway.

Typical 2000 m2 layouts that pass the rule

A three-storey office block of roughly 650 m2 per floor passes easily with the Yagi on the front chimney and panels on the mid-floor core, each separated by the slab above and below. A hotel of 2000 m2 over two floors needs the donor on the roof ridge and the corridor panels below roof level through concrete. A steel-framed single-storey warehouse on one plane uses partition walls, racking banks and office pod divisions as the isolation layer; do not mount a panel on the same wall as the cable entry point, and do not place a panel directly behind the Yagi's roof wall even though 10 m feels like a large distance on paper.

Cable Routing: 10 m Outdoor + 5 m Indoor Coax and the 20/30/40/50 m Upgrade Ladder

The kit contains two separate low-loss coaxial cables with N-type connectors: 10 m for the outdoor donor run and 5 m for the indoor panel run. Keeping them separate matters because each connects to a different port, and the upgrade options apply to the outdoor run, not the indoor one. At 2000 m2 the cable decision is the single most common upgrade question, because roof edge to equipment cupboard distances on enterprise buildings routinely exceed the supplied 10 m and span yards, annexes and separate wings.

The supplied 10 m outdoor cable

Ten metres reaches from a chimney or fascia bracket to the cable entry point on most compact commercial buildings where the amplifier unit sits in a comms cupboard, reception store room or under-stairs space. Route the cable along the eaves, down a drainpipe channel or through a soffit vent; avoid running it parallel to mains power leads, which injects 50 Hz hum, and cross power cables at 90 degrees where you must cross. Use a cable gland or rubber grommet at the drilled wall entry to keep weather out and the cable anchored, and on a commercial roof use UV-resistant clips rather than fixing the coax directly to metal purlins.

The supplied 5 m indoor cable

The 5 m indoor lead runs from the amplifier unit to the panel on the internal wall or ceiling. Five metres covers a cupboard-to-core distance in most layouts. Keep this run as short as possible: every extra metre of passive cable removes signal power from the panel without adding anything in return, and at >=27 dBm output the indoor budget should reach the panel intact, not spend itself in a long indoor extension. Where a floor needs a panel farther from the chassis, add the panel on the MS output through a splitter rather than lengthening the indoor lead by hand.

When to order the 20, 30, 40 or 50 m upgrade at 2000 m2

Order a longer low-loss outdoor cable only when the strongest donor spot cannot be reached with 10 m. The upgrade ladder runs 20 m, 30 m, 40 m and 50 m, and each additional 10 m segment costs roughly 2 dB of passive loss that the >=65 dB uplink and >=70 dB downlink gain budget absorbs but never gives back. A 20 m upgrade suits a site where the Yagi faces a rear field from a side chimney and the unit sits at the front; 30 m suits a deep warehouse, hotel block or workshop across a long floor plan; 40 m suits a pole-mounted Yagi at a field edge feeding a separate office annex; 50 m reserves for the maximum-reach rural enterprise site. Do not over-order: measure the route along the eaves and downpipe, not in a straight line on the map, because cable runs follow walls, corners and risers.

Cable option Typical 2000 m2 layout Rough passive loss Order when
10 m included outdoor Chimney or fascia to central comms cupboard, compact block Baseline Route physically under 10 m
5 m included indoor Unit to central internal panel Minimal Do not extend indoors
20 m upgrade Side chimney or rear bracket to front-of-house core About +2 dB per extra 10 m 10 m cannot reach; route 15 to 20 m
30 m upgrade Deep warehouse, hotel block or long floor plan About +4 dB total Building depth exceeds 20 m
40 m upgrade Pole donor to separate office annex or warehouse far wall About +6 dB total Distributed site, weak donor distance
50 m upgrade Field-edge mast to main commercial building About +8 dB total Maximum reach; pair with high-gain Yagi

Every upgrade length ships as the same N-type low-loss coax with weatherproof connectors, so splicing the included 10 m into a longer run is unnecessary and an unsoldered joint between cables costs more loss than a single continuous upgrade. If you also add the optional lightning surge protector on the outdoor run, place it as close to the cable entry point as practical, because a roof-mounted Yagi on an enterprise building is a taller lightning target than a domestic chimney.

BS and MS Ports: Which Antenna Plugs Into Which Socket

The GDW2000 chassis carries two labelled N-type sockets. BS stands for base station port, the donor input that faces the outdoor Yagi. MS stands for mobile station port, the server output that faces the indoor panel. Getting this pair right is a two-second check but a swapped pair is the third most common support ticket after poor aim and short separation, and at 2000 m2 a swapped pair wastes an afternoon of wall routing before the mistake shows.

BS (base station) = outdoor Yagi

Connect the outdoor cable running from the Yagi to the BS socket, whether that run is the included 10 m or a 20, 30, 40 or 50 m upgrade. This is the input that listens to the serving mast. The amplifier's >=65 dB uplink gain stage takes the phone's faint transmit signal, boosts it through this same path back toward the tower, and the >=70 dB downlink stage boosts the tower's incoming signal out through the MS side.

MS (mobile station) = indoor panel

Connect the 5 m indoor cable running to the 5 dBi panel to the MS socket. This is the output that re-radiates the cleaned signal to phones inside the building, covering up to 2000 m2 through even gain distribution. Plugging the panel into BS and the Yagi into MS reverses the direction of the amplifier: no indoor coverage appears, the AGC sees nothing to lock onto, and the LEDs sit dark or flash without heating up.

Connector habit

Hand-tighten each N-type plug clockwise, then turn a further quarter turn with a spanner or pliers wrapped in cloth. Do not overtighten: an N-type seal does not need wrench force, and crushed threads leak signal on all three bands at once. Check the label on the socket after tightening, not before, because the two sockets sit close together on the rear panel, and label the cable with a tie-on tag at both ends so future maintenance never swaps them on a large building staffed by different technicians.

Power-On Sequence and the AGC Warm-Up Period

Wiring order matters on a repeater because an amplifier powered up with no load on its ports can drive unused ports into reflection, and powering on before antennas are connected gives the AGC a misleading starting point. The safe sequence below takes about five minutes and applies identically whether you fit the standard kit or a 40 m cable upgrade.

  1. Mount the Yagi and run the outdoor cable to the BS port; tighten and label the connector.
  2. Mount the panel and run the 5 m indoor cable to the MS port; check the label once more.
  3. Confirm 10 m separation between antennas and check no metal object, shelving rack, vending machine or lift shaft sits within 30 cm of the panel face.
  4. Leave the AC adapter unplugged until both cables are fully seated and every zone cable route is clipped down.
  5. Plug the AC 100 to 240 V 50/60 Hz adapter into a UK mains socket with a UK 3-pin plug; the unit converts to DC 5 V internally.
  6. Wait 3 to 5 minutes for the per-band automatic gain control to lock onto the donor cells on Band 8, Band 3 and Band 1.
  7. Read the LEDs before moving the Yagi; only re-aim if a band light stays dark or flashing amber.

Why the AGC warm-up is not a cosmetic pause

On first power the amplifier scans the donor spectrum, picks the strongest serving cell per band, calculates isolation against its own re-radiation, and settles gain levels that keep output at or below the >=27 dBm maximum without oscillation. Interrupting that scan by unplugging and replugging mid-warm-up forces it to restart, which is why the wait should be observed once, not repeatedly. On a commercial site where staff keep phones nearby, power the unit on after hours so the first AGC scan is not confused by a room full of active handsets attaching immediately.

Why not power on first?

Some installers plug the adapter in to test the LED before connecting antennas. That habit finds the unit alive but gives the AGC an empty port to chase, and on the next real connection the control loop can sit at an extreme gain setting until a manual cycle clears it. The seven-step sequence avoids that reset every time and keeps the first donor scan clean.

LED Indicators: What Each Light Means During Setup

The GDW2000 uses per-band status LEDs rather than a smartphone app, and reading them correctly replaces the need for constant field-test checks during the warm-up. The lights split into power, donor signal and oscillation categories, and the same logic applies to all three tuned bands.

LED state Likely meaning Action Band affected
Power LED steady green DC 5 V adapter seated; unit on Proceed to band check All
Band LED steady green Donor locked, AGC settled, no oscillation Leave it; test indoors Band 8 / 3 / 1 individually
Band LED dim or amber Donor weak at the Yagi Re-aim toward weakest band; raise height; consider high-gain Yagi The dim band only
Band LED flashing amber Oscillation or overload Increase separation; move panel deeper; never raise gain manually The flashing band
Band LED dark after warm-up No donor on that band, or cable on wrong port Check BS/MS swap; re-survey that band outdoors The dark band
Chassis hot, all lights unstable Continuous oscillation loop Power off; re-separate antennas before restart All

Because the three bands share one antenna pair, oscillation on one band often perturbs the neighbour band's LED as the AGC rebalances. Fix the flashing band first, wait another three minutes, and re-read the others rather than chasing three lights at once. On a commercial site with mains noise nearby, a dim band that stays dim despite good outdoor readings can also indicate the coax run parallel to a heavy power circuit; reroute that section at 90 degrees and restart the scan.

Multi-Zone Testing: Calls, 4G Speed and 3G Fallback Across 2000 m2

Coverage is only proven inside the building, not on the LED panel. After the warm-up settles, walk the 2000 m2 footprint with phones on every network present in the building and check three services in the weakest room, which is usually the loading bay, the top-floor meeting room above the stairwell, the warehouse far corner by the racking, the rear guest bedroom, or the function room at the end of a long hall.

Voice test on Band 8

On an O2 or Vodafone SIM, place a two-minute call from the weakest zone to a landline or a second phone and listen for muffling, echo or sudden drops. A boosted Band 8 link should hold four bars of signal with clear audio throughout; dropped audio that appears only while walking near a window suggests the phone is falling back between boosted and unboosted cells, a tuning matter rather than a fault. For a hotel or office, repeat the call from the basement store and the upstairs meeting suite, because those are the two spots guests and staff call from most.

4G speed test on Band 3

On an EE or Three SIM, run a speed test in the same room and record download, upload and ping. With a donor reading between -97 and -105 dBm at the Yagi, expect a stable LTE link rather than gigabit speed; the goal is a usable session that loads card terminals, video calls, guest Wi-Fi hand-offs and email attachments, not a competitive broadband benchmark. Walk each zone once after the test so the booster does not get blamed for a weak donor reading that was never in the workable range.

3G fallback test on Band 1

Force or wait for a Band 1 session on any network and confirm data loads when 4G is congested. This matters in rural enterprise buildings where Band 1 remains the only data layer after the 4G crowd clears, and it keeps a card terminal or booking page alive when the EE or Three LTE cell is full at peak trading or checkout.

Test in weakest zone Before install After GDW2000 Pass marker
O2/Vodafone 2G call audio 0 to 1 bar, drops 4 bars, clear Two-minute call without drop
EE/Three 4G download 0 to 3 Mbps Stable usable link Video call loads without buffering

Tools, Materials and the 30 to 60 Minute Timeline

The manufacturer's 30 to 60 minute estimate assumes a standard multi-storey office or single-floor warehouse, no ladder work above first-floor gutter level, and the tools below already on site. Extra time on a 2000 m2 site goes to surveying across the whole boundary, aiming and walking every zone; the wiring itself is the shortest phase.

Phase Time Tools needed Key check
Outdoor dBm survey on 3 bands 15 to 20 min Phone field-test mode, compass app All three bands in workable range
Yagi bracket at 3 to 5 m 10 min Masonry drill, bracket, spirit level Beam path clear to mast
Route outdoor + 5 m indoor coax 10 min Grommet, cable clips, gland Separation 10 m; off mains parallel
Connect BS and MS ports 5 min Spanner, cloth, cable labels Labels match antenna direction
Power on and AGC warm-up 3 to 5 min wait Nothing Band LEDs steady green
Zone-by-zone testing 15 to 20 min Phones on all networks Weakest zone passes all 3 services

Extra items worth having on site: a weather boot or self-amalgamating tape for the outdoor N-type connector, a ladder or scaffold platform rated to the working height, cable ties rather than nails through the coax, a cable length measure before ordering the upgrade, and a second pair of hands for the roofline bracket. Listed buildings, conservation areas and commercial leaseholds deserve a quick planning or landlord check for any external antenna, but a single small-business Yagi under permitted development rules rarely needs consent in England and Wales.

Comparison Table: Standard Kit vs Optional Upgrades for a 2000 m2 Site

The table below compares what ships in the box against the paid options, so you order what the building actually needs rather than every accessory at checkout. At 2000 m2 the two justified upgrades are the cable length for a distant bracket and extra indoor panels for separated wings or floors.

Item Included with GDW2000 Optional upgrade Justified for 2000 m2 when
Outdoor antenna 8 dBi Yagi, weatherproof High-gain Yagi upgrade Donor reads below workable floor at all survey spots
Indoor antenna 5 dBi panel Extra panel + splitter Two separated zones, wings or a floor one panel cannot reach
Outdoor coax 10 m low-loss N-type 20 / 30 / 40 / 50 m Bracket position beyond 10 m reach across yard or annex
Indoor coax 5 m low-loss N-type Not recommended Keep short; extension wastes output
Power adapter AC 100-240 V to DC 5 V, UK 3-pin Surge protector Yagi on tall roof mast or exposed enterprise roofline
Gain per band >=65 dB up / >=70 dB down No manual gain dial AGC handles balance automatically
Output power >=27 dBm max Fixed by regulation Ofcom licence-exempt ceiling
Coverage / users 2000 m2 / 200 users Second panel split Large footprint with distant annex, wings or multiple floors

Expanding Coverage: Extra Indoor Antennas for a Multi-Zone 2000 m2 Site and 200 Users

The GDW2000 is rated for 2000 m2 and up to 200 simultaneous users, and the single 5 dBi panel covers that footprint when the amplifier sits at the building core. Some 2000 m2 layouts, however, split into zones that one panel cannot reach evenly: a main warehouse plus a detached office block, a hotel over two floors plus a function suite, a long office hall where one panel sits at the end rather than the middle, or a showroom with separate storage annex.

When a second panel helps

Add an extra indoor panel through an N-type splitter on the MS output when the weak room sits more than about 15 m from the first panel and two solid walls or a steel racking bank away from it. The amplifier's >=27 dBm output budget supports a modest split across two radiating points without collapsing either signal; the splitter costs 3 to 5 dB of shared power, which the >=70 dB downlink margin absorbs for two panels but not for three or more. For a genuinely split campus with buildings tens of metres apart, a second booster unit rather than a long splitter run is the correct answer.

User load of 200 simultaneous connections

The 200-user rating counts active phone sessions on the boosted cell, not registered devices. A 40-person office, a 30-room hotel and a mid-size warehouse staff use only a fraction of that headroom; a busy showroom, conference event or retail floor pushing close to 200 concurrent calls approaches the ceiling and should rely on the main network beyond it. The unit is not a stadium or distributed antenna system and the 200-user rating should not be overstated in planning a public venue.

Do not split the outdoor side

Extra indoor panels split the MS output, never the BS input. Two Yagis on the donor side feed two different cells and invite oscillation and confusion in the AGC, so expansion on the outdoor side means a longer or higher-gain cable and better aim, not a second donor antenna. This rule holds even on a 2000 m2 site where it is tempting to bolt a second Yagi to each wing.

Common Installation Faults and Fixes on a 2000 m2 Site

Fault 1: A band LED stays dark after warm-up. Check the BS and MS labels first, then re-survey that band outdoors. A dark Band 3 light on an EE customer usually means the donor 4G was never present at the Yagi position; moving the bracket to the side elevation that reads -105 dBm or better fixes it.

Fault 2: Flashing amber oscillation LED. Increase vertical separation, move the panel deeper inside, or reposition an intervening wall or slab. Do not attempt to lower output manually; the AGC already sits at the Ofcom-legal ceiling of >=27 dBm output and the only real fix is geometry.

Fault 3: One distant zone stays at zero bars. Measure the distance and wall count from the panel. Beyond 15 m through two walls or a steel aisle, add a second panel on the MS output rather than re-aiming the Yagi, because the donor side was never the problem in that room.

Fault 4: Call audio muffled despite steady green LEDs. Look for the panel mounted behind foil-backed plasterboard, inside a metal cupboard, behind a steel shelving rack or inside a lift shaft; move it to a plain internal wall or ceiling with 30 cm of clear space in front.

Fault 5: 4G speed rises then drops a minute after testing. Classic oscillation loop. Power off, increase separation, and restart the three-minute AGC scan from a clean state rather than chasing the gain setting.

Fault 6: Connector corrosion on the outdoor plug. The weather boot was omitted or the connector faced upward. Reseat with fresh self-amalgamating tape and angle the plug downward so water drains away, particularly on an exposed enterprise roof.

Fault 7: The 10 m included cable falls short of the bracket. Do not splice or stretch; order the measured 20, 30, 40 or 50 m continuous low-loss upgrade, because a joined run loses more signal than a single clean length.

Bottom line in plain terms: the GDW2000 installation on a 2000 m2 enterprise site succeeds when the outdoor survey lands a workable reading on Band 8 between -76 and -90 dBm, Band 1 between -80 and -94 dBm and Band 3 between -97 and -105 dBm, the 8 dBi Yagi mounts 3 to 5 m high on a clear bearing to the serving mast, the antennas stay 10 m apart vertically, the outdoor coax feeds the BS port and the 5 m indoor coax feeds the MS port, the outdoor run is upsized to 20, 30, 40 or 50 m only where the route demands it, power follows wiring rather than precedes it, and the per-band LEDs settle green during the AGC warm-up before any zone test. The standard kit covers most warehouses, hotels and large offices; extra panels appear only when geometry genuinely demands it. Allow 30 to 60 minutes, ordinary DIY tools, and a phone in field-test mode, and remember the unit is UKCA and CE certified and Ofcom licence-exempt, so no installer and no frequency licence are required.

Frequently Asked Questions

How many indoor panels does a 2000 m2 warehouse, hotel or large office need, and when do you split the MS output?

The GDW2000 ships with one 5 dBi panel and covers the rated 2000 m2 when the 3.0 kg amplifier sits near the geometric centre of the floor plan. Add a second panel through an N-type splitter on the MS output only where a weak zone sits beyond roughly 15 m from the first panel through two solid walls, a steel-racking aisle, or a separate hotel wing. The splitter costs 3 to 5 dB of shared power, which the >=70 dB downlink margin absorbs for two panels; a genuinely split campus with buildings tens of metres apart needs a second booster unit rather than a long splitter run, and the BS donor side is never split.

Can the GDW2000 handle 200 simultaneous phones at a busy reception, event floor or hotel checkout?

The GDW2000 supports up to 200 simultaneous active sessions on the boosted cell, which comfortably covers a 30 to 60 person office, a hotel with guest phones on standby, a warehouse with staff and forklift radios, or a retail event floor. The rating counts active calls and data sessions rather than registered devices; beyond the ceiling the serving tower schedules phones itself, which is a network limit, not a booster fault. A public venue approaching 200 concurrent calls should rely on the main network beyond the covered footprint rather than treating the repeater as a stadium system.

How do I lay out the amplifier and panels across multiple floors of a large office block?

Mount the chassis on a wall or comms cupboard near the building core on a mid floor, run the MS panel leads vertically through the riser, and place one panel per floor where the open-plan desks cluster. Keep the donor Yagi on the highest accessible roof face, maintain the 10 m vertical separation between Yagi and the nearest panel, and never place a panel directly behind the Yagi roof wall. Each floor's panel should see open office floor; panels inside server rooms, behind steel filing racks or inside metal cupboards lose the >=70 dB gain before it reaches the desks.

Where exactly do I measure the outdoor coax route before choosing the 20, 30, 40 or 50 m upgrade for a 2000 m2 site?

Measure the physical route along the eaves, down a drainpipe or riser and through the wall entry, not the straight-line map distance: cable follows corners and bends. The included 10 m outdoor cable reaches a chimney or fascia bracket to a central cupboard on compact sites; order the 20 m upgrade when the bracket sits across a yard, 30 m for a deep warehouse gable to the office core, 40 m for a pole-mounted donor feeding a separate annex, and 50 m for a maximum-reach rural enterprise site. Every extra 10 m costs roughly 2 dB of passive loss absorbed by the >=65 dB uplink and >=70 dB downlink budget, so match length to the measured route.

How should I align the 8 dBi Yagi when the serving mast sits behind a hill, tree line or neighbouring block?

The 8 dBi Yagi focuses a narrow forward beam, so first find the bearing to the serving mast in a survey or network app, then raise the bracket to 3 to 5 m above roofline or chimney height to clear the obstruction. Sweep the Yagi slowly in small 5-degree steps while watching the band LED or a field-test phone, and lock the position at the strongest steady green reading. A blocked beam with a cheap short cable never beats a clear beam with a slightly longer one; if no angle clears the obstacle, raise the pole or add the optional high-gain Yagi rather than forcing aim at a shadow.

What multi-zone test covers loading bays, meeting rooms, guest bedrooms and warehouse far corners after install?

After the 3 to 5 minute AGC warm-up, walk each zone with a phone on every network present: place a two-minute O2 or Vodafone Band 8 call from the loading bay and a top-floor meeting room, run an EE or Three Band 3 4G speed test in the warehouse far corner and a rear guest bedroom, and confirm a Band 1 3G session loads where 4G is congested. A zone stuck at zero bars after the walk needs an extra MS panel or a moved panel, not a re-aimed Yagi, because the donor side was never the problem there.

Does the 3.0 kg chassis need rack mounting, ventilation clearance or a dedicated UK mains socket in a comms cupboard?

The 3.0 kg GDW2000 mounts on a wall bracket or shelf; leave 15 to 20 cm of clear air around the case and keep it away from heaters, kettles and unventilated sealed cupboards. It runs from the AC 100 to 240 V 50/60 Hz adapter stepping down to DC 5 V with a UK 3-pin plug, so any standard UK socket works; use the optional surge protector when the Yagi sits on a tall commercial roof. The operating range of -10 C to +55 C means normal winter and summer indoor placement is fine, but a sealed plant cupboard overheats the AGC and triggers back-off.

How does panel placement differ between a long hotel corridor and a steel racking warehouse?

A hotel corridor works best with one ceiling panel at the corridor midpoint feeding rooms on both sides, because doors and plasterboard are thin and the >=70 dB downlink reaches both wings evenly. A steel racking warehouse reflects and absorbs 2100 MHz heavily, so place panels low between rack aisles rather than high on the wall, split the MS output across two radiating points, and test at forklift eye level. In both layouts avoid mounting the panel behind foil-backed lining, inside a metal duct, or within 30 cm of a shelving rack or lift shaft.

What is the correct outdoor surge protector placement and weatherproofing on an enterprise roof install?

Fit the optional lightning surge protector as close to the building cable entry as practical, so the protected run between protector and Yagi is short and the long indoor side sits behind the arrestor. The weatherproof Yagi itself is sealed, but the N-type connector is not: seal it with the weather boot or self-amalgamating tape, angle the plug downward so rainwater drains away, and use UV-resistant clips rather than strapping coax to metal purlins. On a tall warehouse or hotel roof the elevated Yagi is a lightning target, which is why the arrestor earns its place on exposed commercial installs.

If one band reads weak outdoors during the enterprise survey, can I still install the GDW2000 on a 2000 m2 site?

A repeater can only amplify a donor it receives, so a band that reads below its workable floor at every outdoor position cannot be manufactured indoors. You may still improve the other two services, but the missing band stays missing: raise the bracket, extend the pole to clear the obstruction, or add the high-gain Yagi before committing. Remember O2 and Vodafone 4G on Band 20 at 800 MHz are outside this unit's design entirely, so a weak Band 3 reading on an EE site and a missing Band 20 reading for O2 are two different problems with two different answers.
