Answer first: complete an enterprise site survey with the target EE, BT, ASDA, Virgin, O2, Vodafone and Three SIMs before fixing anything, then mount the included high-gain Yagi high and clear on the HQ rooftop, mast, chimney stack or gable, aim its boom toward the serving mast with a clear line of sight and vertical elements, and keep it at least 10 m vertically separated from every indoor antenna. Run the 10 m outdoor coax to the BS donor port, run the 5 m indoor lead from the MS server port to the main whip, leave the 5V adapter unplugged until all antennas and the splitter tree are connected, then power on and read the LED. Add the cascaded 2/3/4-way splitter tree and a second through tenth whip only when the outside donor is strong, placing each antenna in a separate floor, warehouse bay, guest wing, hospital corridor, classroom block or estate zone away from the Yagi lead. Test EE-family voice calls and all-network 3G data across the main tower, meeting suites, upper floors, logistics bays, visitor wings and estate zones for up to 200 handsets before go-live. The DW2000 suits EE-business accounts and mixed-carrier enterprise premises that need reliable voice calls plus an all-network 3G fallback across a 2000 m² site; it cannot create signal where the phone already reads zero bars outside, carries no Band 20 rural 4G on 800 MHz, carries no Band 8 on 900 MHz, and does not carry 5G.

What Comes in the DW2000 Enterprise Kit Before the Site Survey

Open the box on a clean table before running any cable. The standard DW2000 kit contains the booster chassis, the high-gain Yagi directional outdoor antenna, the 3 dBi indoor whip antenna, the UK Type power adapter, the 10 m outdoor coax, the 5 m indoor coax and the mounting hardware; the multi-way splitters and any extra indoor whips or riser leads form the expansion tree used to spread the field to ten interior antennas across a 2000 m² enterprise site. No drilling, crimping or soldering is required for the core three-stage install, and the unit carries a 365-day money-back guarantee with lifetime technical support.

Checks before the aerial leaves the table

Confirm the phone already reads one or two bars outside the premises on the target EE, BT, ASDA, Virgin, O2, Vodafone or Three SIM; the repeater amplifies an existing weak donor and cannot manufacture a block the mast does not transmit. Check the Yagi elements are straight and undamaged, the base seal sits flat to the bracket, both N-type connectors screw firmly, the indoor whip has its own base and lead, and the chassis vents are clear in the planned comms cupboard or rack position. Automatic gain control inside the chassis balances the level as handsets move between floors and zones, so clean antenna separation and a well-aimed Yagi matter more than manual tuning. The DW2000 covers up to 2000 m² with 200 simultaneous users; an HQ tower, distribution centre, hotel, hospital, school, campus, conference centre or large estate fits that footprint naturally, while a multi-building campus over 2000 m², a separate factory unit behind the main yard, or two independent enterprise premises should plan a second repeater rather than overloading one chassis, one riser and a ten-antenna tree.

Step 1: Enterprise Site Survey and Yagi Rooftop or Mast Aiming

The DW2000 enterprise kit ships the directional Yagi because a 2000 m² HQ, warehouse, hospital or estate often reaches a distant donor mast across car parks, rooftops, ridge lines, open fields or neighbouring industrial yards; the Yagi concentrates the receiver toward that single bearing and pulls a stronger combined Band 3 and Band 1 block through the chassis than a broad omni could at this distance. Both the 1800 MHz EE-family layer and the 2100 MHz all-network 3G layer arrive through the same Yagi element set, so the aim point must suit the combined reading rather than one carrier alone.

Walk the site before you fix the bracket

Carry the EE-family SIM and an O2, Vodafone or Three SIM around the front entrance, rear car park, rooftop edge, gable position, loading yard, property boundary and each ground-floor lobby, noting the bar count and data speed at each point. Identify the bearing that gives the strongest combined reading rather than chasing one strong carrier on its own; a Yagi locked onto a distant O2 mast can miss the EE 1800 MHz layer entirely and leave enterprise voice calls dead indoors. Mark the rooftop, gable or chimney position that faces that strongest bearing, and take the reading again at the planned bracket height, because roof-level signal often differs from street-level entrances. For a mixed-tenant building, record which carriers staff, visitors and services actually use so the aim protects the business-critical EE voice layer alongside the all-network 3G fallback.

Mounting points and clear line of sight

Fix the Yagi to a rooftop ridge bracket, chimney strap, gable mast or rear wall bracket with an unobstructed sky view toward the chosen mast; keep it above the parapet, solar panel edges, TV aerial, extractor vents, tall hedges, plant rooms and neighbouring rooftop plant that could shade the bearing. At 1800 MHz and 2100 MHz a dense treeline, a ridge line, a neighbouring multi-storey block or a high rack inside the building can break the first clear Fresnel zone between mast and aerial; raise the Yagi on a short mast until the bearing reads clear rather than accepting a hidden fourth-floor position. The Yagi boom points horizontally toward the mast, with the longer reflector and director elements stacked vertically.

Polarization and elevation

UK mobile masts transmit vertically polarised signals on these bands, so keep the Yagi elements vertical and the boom horizontal; a 90-degree rotation across the boom cuts the received block by several dB before the chassis adds any gain. Where the serving mast sits on a distant hill, beyond a neighbouring town or across a wide industrial yard, tilt the Yagi gently upward on the bracket to track that elevation rather than leaving it level; do not lean it sideways to chase a corner signal, because that defeats the vertical polarisation alignment.

The fine-tune after the first power-up

Loosen the bracket, sweep the Yagi slowly across the chosen bearing while watching the bar count on both an EE-family SIM and an all-network SIM indoors, settle on the peak combined reading, then lock the bracket and reseat the connector. Recheck the aim after the indoor whips are live: a Yagi that looks well placed on the rooftop may respond to a small swing of ten to twenty degrees that raises both Band 3 calls and Band 1 data at the far warehouse bay, hospital corridor or estate wing.

Step 2: 10 m Vertical Isolation and the Riser and Trunk Cable Runs Across Floors

The 10 m vertical separation rule applies between the rooftop Yagi and every indoor antenna on this enterprise chassis, because the amplified interior field must not feed straight back into the donor aerial and latch the gain stage into oscillation. The fixed 10 m outdoor coax runs from the Yagi to the chassis; the separate 5 m indoor lead runs from the MS port to the main whip in the central usage area, with splitter-tree branches feeding the second through tenth whips further inside the premises.

How the separation works on a multi-storey enterprise building

On a three or four-storey HQ tower, hospital or campus block, the Yagi sits on the rooftop or upper gable, the main 3 dBi whip stands on the central ground-floor lobby or central aisle, and the second through tenth whips occupy upper offices, the rear warehouse bays, the hotel guest wing, hospital corridors, classroom blocks or estate zones on separate levels. That vertical fall keeps the donor aerial and server antennas out of direct radio contact. On a single-storey distribution centre, factory or large exhibition hall without a 10 m fall, place the Yagi and the whips on opposite external walls, route the leads on separate sides of the building, and accept that usable gain will sit below the 10 m separation design; clustering every whip near the same donor wall or above the Yagi bracket is the most common cause of a flickering, unstable LED after power-on.

Sealed outdoor entry and tidy enterprise routing

Run the outdoor feed down a gutter channel or rooftop edge, enter the premises through an existing drilled masonry grommet, a window frame gap or a dedicated sealed wall entry with a weatherproof gland. Leave a drip loop where the cable exits the wall so rainwater runs away rather than down the lead, then tuck the outdoor coax behind skirting, door architrave or commercial trunking on its way to the chassis position. The 5 m indoor lead leaves the MS port and clips behind the same hallway trim, bar paneling or skirting to the main whip position; keep it separate from the outdoor coax run so the interior field does not couple onto the donor lead. Above the ground floor, the riser lead climbs a dedicated service shaft alongside the building electrics, held on riser clips every 30 to 40 cm, with separate trunking to each floor cabinet. Avoid running either coax alongside mains electrical cable for long sections; cross the mains run at a right angle rather than parallel, and clip both leads every 30 to 40 cm so they do not hang loose behind counters, filing racks, reception screens, guest-room trays or rack aisles. Keep both leads away from TV aerial coax, kitchen appliance leads, server power bricks, ventilation ducting and building automation wiring to prevent interference on Band 3 and Band 1.

When the 20 / 30 / 40 / 50 m outdoor upgrade applies

The fixed 10 m outdoor lead reaches a rooftop donor down to a ground-floor chassis in a typical enterprise premises; if the strongest donor point sits beyond that distance — a distant chimney stack on a wide car park, a separate factory behind the main yard, a hotel ridge position far from the service cupboard, or a warehouse mast at the estate boundary — order a 20 m, 30 m, 40 m or 50 m low-loss outdoor upgrade. Longer outdoor coax adds signal loss at the donor stage, so a stretched cable on a weak donor reads worse than a short cable on a strong one; check the outside bar count first, then match the outdoor cable length to the distance rather than assuming more cable always helps. Splices in a self-routed coax should be avoided: a poorly joined run adds loss and moisture risk that the 70/75 dB gain cannot fully recover. The 5 m indoor lead covers the main whip from chassis to central zone; whips on upper floors, distant bays or separate wings use the splitter-tree expansion described later rather than over-stretching this fixed indoor length.

Step 3: Chassis Placement and the BS versus MS Ports

The compact 170 × 110 × 30 mm chassis, about 450 g, fits on a reception shelf, inside a comms cupboard, behind a TV unit, in an IT back-room recess, under a warehouse office desk, on a hotel housekeeping shelf, in a hospital electrical cupboard, on a school store-room shelf or in an estate service cupboard; it needs ventilation, must sit away from direct heat, radiators, kitchen ovens, boiler housings and server rack exhaust fans, and should stay reachable for the LED check and a future facilities handover. The two ports are labelled, and swapping them inverts the amplifier loop and causes oscillation.

The BS port faces the donor mast; the MS port faces the interior users. Connecting the Yagi to MS and the whips to BS lets the interior field repeat through the donor aerial back toward the mast, feeding the stage a second loop that the automatic gain control cannot balance. Match the labels before applying power, and do not swap leads while the adapter is live.

Where the 3 dBi whips radiate best across 2000 m²

Place the main indoor whip in the central usage area — reception centre, hallway between meeting rooms, office aisle centre, lobby between warehouse zones or hotel housekeeping lobby — upright and clear of metal cabinets, filing racks, beer kegs, kitchen fridges, chrome optics and thick concrete partitions. Keep it one to two metres from the chassis and away from the outdoor coax route, so the room field does not couple onto the external lead. In a split HQ and warehouse layout, the main whip should sit central to both spaces before the second through tenth whips are added through the splitter tree. Lay the indoor leads behind counters, bar paneling, desk modesty panels or skirting rather than across a walkway, and keep each whip upright rather than folded behind a bookshelf, reception screen, pub optics shelf or warehouse rack beam.

Where the chassis sits in each enterprise space

In an HQ tower, tuck the chassis in a comms cupboard or IT rack recess with the vents clear; in a distribution centre, on the office-side shelf of the connecting workshop; in a hotel, on the housekeeping shelf near the guest corridor; in a pub or conference venue, under the service counter in a ventilated bracket; in a hospital, in the plant-room cupboard away from medical equipment heat; in a school, on the main-store shelf away from the heating radiator; in a rural estate, on the main-building side of the connecting door rather than on the cold steel bench itself. The chassis should remain visible enough to read the LED during the 200-user test but hidden from staff, guests, patients, pupils and stored stock. The rated operating range from minus ten to plus fifty five degrees Celsius covers a normal heated premises and a sheltered garden room, but a bare uninsulated barn that freezes in winter, a cellar bar against an unheated boiler room, or a kitchen recess beside an oven should use a sheltered chassis position away from that heat source.

Step 4: 5V DC Power, Power-On Order and the Status LEDs

The booster runs on the included UK adapter, input AC 100–240 V 50/60 Hz, output DC 5V. The installation order protects the radio stage: antennas first, power last, so the chassis never wakes into an open or self-fed loop.

Correct power-on sequence

First the Yagi is fixed and the 10 m outdoor coax reaches the BS port; second the 5 m indoor lead and main whip connect to the MS port, with any splitter-tree branches and extra whips fitted and spaced away from the donor; only then the 5V adapter is plugged into the mains socket. Powering the booster before the MS side is connected lets the chassis radiate into an open port and can trigger oscillation in a confined reception room, bar area or office aisle. Once power is applied, wait ten seconds for the LED to settle, then compare phone readings near the main whip against the outside donor count before stepping back to the installation review.

The 18 KA surge protector on the rooftop or mast run

On an HQ block, hotel, hospital, rural warehouse or conference centre with the Yagi on the ridge, chimney strap or elevated mast, fit the optional 18 KA lightning surge protector in the 10 m outdoor coax run near the building entry, bonded to the building earth where available. The surge protector drains a lightning-induced voltage spike before it reaches the chassis or the room network; it does not make the premises lightning-proof, and regular earth bonding and roof protection remain separate electrical jobs. On a flat single-storey unit with an internal landing bracket the protector is less critical, but it is the recommended upgrade on any elevated external mount, particularly a rural estate or farm struck more often by summer thunderstorms.

Step 5: Multi-Way Splitter Tree — Up to Ten Indoor Antennas Across HQ Floors, Bays and the Whole Building

The DW2000 supports up to ten indoor antennas through a cascaded tree of 2-way, 3-way and 4-way dividers, the 2000 m² enterprise expansion class for a second reception floor, an upper HQ level, a rear warehouse bay, a meeting-suite wing, a hotel guest corridor, a hospital ward, a classroom block, a shopping arcade unit or an estate zone beyond the main usage area. The source guidance states, verbatim, "Expandable coverage by adding indoor antenna, splitter, cable if the outside signal is strong."

How the cascaded tree adds a second through tenth zone

After the main whip serves the central lobby, bar or office aisle, fit the first-stage divider on the MS side, run riser and trunk leads to floor or zone cabinets, and in each cabinet fit the second-stage divider that feeds the local whips: the second whip in the rear reception or meeting suite, the third on the upper HQ floor, the fourth in the warehouse bay, the fifth in the hotel guest wing, the sixth in the hospital corridor, the seventh in the classroom block, the eighth in the retail arcade, the ninth in the conference wing, and the tenth in the estate outbuilding that sits beyond the main partition. Spacing every antenna away from the Yagi and its outdoor lead keeps the feedback loop open. A passive cascade sheds signal at every divider: a 2-way first stage loses roughly three to four dB per arm, a 3-way or 4-way first stage loses roughly five to seven dB per arm, and each second-stage divider adds another three to seven dB before the branch lead loss. That is why the main whip normally keeps the strongest reading, while the second through tenth whips hold a usable but lower field in their own zones. The ≥70/75 dB gain and series-high ≥27 dBm enterprise output on this flagship chassis supply the headroom for those ten branches across a wide site, which is the radio reason this enterprise tier rather than a lower chassis supports the ten-antenna tree over a large footprint.

Splitter placement, antenna density planning and the loss budget

Mount the first-stage divider close to the chassis on the MS side rather than at the far end of a long trunk, so the shortest possible main lead reaches the floor cabinet. In each floor or bay cabinet, place the second-stage divider near the cluster of local whips rather than at the far end of a long riser. Plan the antenna density before drilling: one whip per roughly two hundred square metres of open-plan space in the first pass, rising to two per floor in a heavily partitioned suite, with spare branch ports reserved for a future extension. Place each whip upright in its zone centre, away from metal partitions, rack beams and service-duct shafts; label each branch at the chassis and each cabinet so a future facilities visit knows which whip serves which floor, bay or wing, and keep a written loss budget against every riser, trunk and branch lead length for the enterprise records. Do not bury a divider inside a metal cupboard where the shielded enclosure can attenuate the branch feeds, and keep every indoor lead separate from the outdoor coax run.

When not to split, and the shared 200-user limit

On a weak donor, a splitter tree just divides a faint signal across ten zones and leaves all spaces weaker than a single well-placed whip. Do not daisy-chain extra dividers beyond the planned two-stage tree on this chassis, and do not add a whip into a concrete-partitioned room, a steel warehouse bay or a separate outbuilding that the Band 3 and Band 1 signals cannot reach from the main chassis; a separate repeater in that zone is the correct route. The 200-user limit is shared across all ten whips, so an HQ, hospital or warehouse with more than two hundred active handsets should move to a higher coverage tier or a second repeater rather than overloading the tree. If a far whip reads zero bars on arrival, reseat its branch connector at both the cabinet and the divider, check the splitter port, and confirm the donor outside still reads one to two bars before assuming the tree failed.

Step 6: The 200-User Enterprise Load Test Across 2000 m²

The DW2000 supports up to 200 simultaneous handsets sharing the boosted field; in an HQ that means staff mobiles, meeting-room laptops, desk phones, a reception handset and a connected building hub, while a hotel, hospital, school, warehouse or arcade spreads the load across staff phones, booking tablets, a till terminal, guest hotspot devices, card terminals, a Wi-Fi-enabled POS system, clinical devices, school tablets, warehouse scanners and a building automation hub.

How to run the test before go-live

Park the premises where the outside phone reads one to two bars. Place mixed EE, BT, ASDA, Virgin, O2, Vodafone and Three SIM phones near the main whip, then move handsets to the upper HQ floor, rear warehouse bay, meeting-suite wing, hotel guest corridor, hospital ward, classroom block, retail arcade unit or estate zone. Start a Band 3 voice call on an EE-family SIM and a Band 1 3G data session on an O2, Vodafone or Three SIM at the same time, hold both for a minute, and walk the reading around the main spaces and any split second through tenth zone. Record the bar count before the booster, after fitting near the whip, and at the furthest point; compare against the outdoor donor so the test reflects amplification rather than a strong mast that would have worked anyway. Stagger hotspot sessions so the gain stage balances two hundred handsets rather than piling every device on one antenna at once, and repeat the walk-through at busy times for a hotel, hospital, school, conference venue or arcade with opening-hour trade.

DW2000 Against the 2000 m² Range: Why Band 3+1 Adds EE Voice and 3G

The Boost4U 2000 m² enterprise range splits by tuned band; the DW2000 pairs Band 3 1800 MHz with Band 1 2100 MHz, so choosing the wrong combo leaves either the EE voice call layer or the all-network 3G data layer unboosted.

Pick the DW2000 for an EE, BT, ASDA or Virgin enterprise account and a mixed-carrier HQ, warehouse, hotel, hospital, school, conference centre or estate that needs voice calls to hold through the lobby, meeting suites, upper floors, far bays, guest wings and estate zones, while O2, Vodafone and Three members still get 3G data and voice on Band 1 across 2000 m². Choose the CD2000 where the priority is EE, O2 and Vodafone 4G data on an 800 MHz rural layer with no call band requirement; choose the CG2000 for O2/Vodafone rural 4G plus legacy 2G voice without the modern EE or 3G layer; choose the CW2000 for O2/Vodafone rural 4G plus 3G on every network but without EE voice; choose the DW1000 only where the premises stay within a 1000 m² footprint and hundred-user load, and the DW500 for a 500 m² large home or medium business. The DW2000 fills the voice-plus-3G gap on the 2000 m² enterprise tier with the ten-antenna tree, the high-gain Yagi in the box and the series-high ≥27 dBm output.

Troubleshooting: Oscillation, Weak Donor, Splitter-Tree Imbalance, Dead Zones, No EE Voice, No 3G and the LED Read-Out

Oscillation: feedback loop and flickering LED

The symptom is a flickering LED, a reading strong beside the main whip but fading a metre away, and dropped sessions despite power. Causes are a BS/MS port swap, an interior whip mounted too close to the Yagi or its outdoor coax, a tree branch routed alongside the outdoor feed, or the chassis sited beside the donor aerial where the interior field feeds the donor directly. Swap the ports if reversed, move the whips one to two metres away, keep the indoor and outdoor leads on opposite sides of the premises, check every cabinet divider and branch connector, and let automatic gain control settle before retesting on a parked install.

Weak donor and mis-aimed Yagi

If both bands read faint indoors despite a steady LED, the Yagi may face the wrong mast, a treeline or a ridge line, or the outside donor itself may sit at zero bars. Walk the perimeter with each SIM, re-aim the Yagi across the bearing sweep, reseat the outdoor connector, and verify the donor count at rooftop height before opening the chassis. A distant mast behind a ridge often needs a raised mast position or the 20 to 50 m cable run to reach the clearest bearing on the estate boundary.

Splitter-tree imbalance and dead zones

If the main lobby reads strong but the upper HQ floor, warehouse bay, hotel corridor or hospital ward reads weak, the likely causes are a loose second-stage branch connector, an over-long riser or trunk lead, a whip hidden behind a metal partition, a divider buried in a metal cupboard, or a weak donor that cannot support ten branches. Reseat every cabinet and divider connector, move the weak-zone whip toward that zone's centre, shorten the branch lead where possible, verify the outside donor still reads one to two bars, and on a weak donor remove the last two or three whips until the donor improves rather than forcing the full ten-antenna tree.

No voice on the EE-family SIM

If an EE, BT, ASDA or Virgin handset cannot call indoors but 3G data works on another SIM, check the Band 3 layer first: the Yagi may face an O2 or Vodafone mast bearing that does not serve the EE 1800 MHz band, the donor reading outside may be too weak for Band 3 alone, or the Yagi may have been aimed at the wrong mast during the fine-tune. Walk the premises outside with the EE SIM, find the strongest 1800 MHz bearing, re-aim the Yagi toward it, and verify the Band 3 voice call holds after refit. A phone that has disabled its network mode, or a legacy handset stepped off the 4G packet layer, should be checked in the handset settings rather than blamed on the chassis.

No 3G on an O2, Vodafone or Three SIM

If the Band 1 3G data session will not connect on a non-EE SIM while EE-family calls hold, confirm that the local mast still transmits 3G in that street, reseat the MS whip lead and every cabinet divider connector, and check that the donor outside reads at least one bar on that carrier's SIM. A host network that has retired 3G in a local area shows its own fallback behaviour; the chassis amplifies what the mast transmits, it cannot create a missing 3G layer. A weak reading that strengthens after swinging the Yagi a few degrees confirms the aerial aim was the limiting factor rather than the chassis gain.

Metal structure and mains noise across the enterprise site

A far bay that drops while the main lobby holds is a coverage footprint issue: move the whip toward that corner, add the appropriate tree branch whip if the donor is strong, or accept the 2000 m² limit and plan a second repeater for a multi-building campus over 2000 m², a large function complex or a separate outbuilding. A steel workshop, insulated warehouse bay or separate barn that will not receive the field needs its own donor and chassis rather than a whip pushed through a thin partition. Hiss, clicks or data dropout that track the kettle, espresso machine, server rack, pub fridge, clinical equipment or warehouse washing machine point to mains coupling: separate both coax leads from the power wiring, check the adapter fuse, and keep the chassis away from the fuse board, kitchen supply rack, bar electrical distribution and medical equipment supply.
