Answer first: mount the included high-gain Yagi high on the rooftop mast, chimney or gable, rotate its narrow beam toward the serving mast until the outside phone reading peaks, keep it at least 10 m vertically above and separated from the indoor whips, run the 10 m outdoor feed through a sealed entry to the BS donor port and the 5 m indoor feed from the MS server port to the splitter trunk, plug the Yagi lead into BS and the whips into MS, power the 5V DC adapter after both antennas are connected, read the steady LED, and test data plus 3G calls across the 2000 m² space with up to 200 handsets; the core job takes 10 to 15 minutes with no tools, a long rooftop reach triggers the 20 to 50 m outdoor cable upgrade, an exposed mast justifies the 18KA surge protector, and a strong outside reading funds the stacked multi-way splitters with up to nine extra indoor whips across ten zones. The CW2000 suits an EE, O2, Vodafone or Three enterprise premises spread over multi-floor HQ floors, hotel wings, warehouse bays or mall aisles that loses 4G data and the 3G fallback indoors; it does not carry 2G voice on Band 8 or Band 3, does not do 5G, and stays rated for 2000 m² rather than a multi-building campus.

What Comes in the CW2000 Full Kit Before You Start

Confirm the box before the first U-bolt or mast clamp. The CW2000 full kit already contains the high-gain Yagi directional aerial, the booster chassis, the 3 dBi indoor whip, the 10 m outdoor low-loss feed, the separate 5 m indoor low-loss feed, the UK 5V DC power adapter and the mounting bracket; the 20/30/40/50 m outdoor cable, the 18KA lightning surge protector and the stacked multi-way splitters with extra whips are ordered upgrades rather than standard parts.

Tools you actually need for an enterprise mount

No crimping or soldering is required for the standard install: a drill or bracket for the gable or mast clamp, a sealed entry grommet for the outdoor feed, a phone field-strength read-out for aiming the Yagi, and a spanner for the U-bolt. Keep the Yagi elements clear of roof plant, glass atriums, pipework and metal frames, keep both feeds coiled loosely rather than twisted, and survey the outside donor reading before choosing the cable length or splitter layout. The 27 dBm output has the headroom to feed ten whips across the premises, but that headroom only reaches the far floor, wing and aisle if the indoor antennas are spread rather than clustered beside the chassis.

Step 1: Mount and Aim the Included Yagi at the Serving Mast

The Yagi is a directional panel: it focuses a narrow beam on one mast and rejects clutter from other directions, which is exactly the weak-signal capture a large enterprise rooftop needs. Unlike an omni, it must be pointed; aim decides the reading more than height does, and on a multi-floor HQ the beam path must clear the rooftop antenna farm and glass atrium.

Find the mast direction before you fix the clamps

Walk the roof edge or the car park with the phone on the same EE, O2, Vodafone or Three SIM used inside, note which direction the bar count and RSRP peak, and point the Yagi elements' long axis toward that bearing. On a Devon corporate headquarters, a Yorkshire hotel or a Wales warehouse, customers reported the included Yagi and the high output took a single bar to five across the whole space; that jump comes from aiming the beam at the serving tower rather than from the chassis alone. Use a compass or the phone's direction finder, and re-check the reading after rotating the panel a few degrees each way before tightening the clamp.

Mount high, clear of rooftop plant, atriums and steelwork

Fix the Yagi on the rooftop mast, chimney stack, roof ridge or gable wall where its beam path to the mast stays clear of AC units, pipe runs, lift housings, glass atrium screens and overhead steel; a panel mounted behind a solid gable face, a duct bank or a glass-walled stair tower sees the structure rather than the tower. Keep the elements horizontal or vertical as the radio standard requires, tighten the U-bolt, and leave enough free play to fine-aim after power-up. The narrow beam tolerates a few degrees of error but not a 30° miss, and metal screens between the panel and the tower cut the donor more than the gain can recover.

10m vertical separation between Yagi and indoor whips

Keep the Yagi at least 10 m vertically above the nearest indoor whip and on the opposite face of the building where possible. This gap, the antenna isolation, stops the whips radiating the amplified field straight back into the Yagi, which would make the chassis feed its own output and oscillate; at the 27 dBm enterprise output, a leaky separation regenerates harder than on a 20 dBm unit, because the stage has more power to feed back. On a tall hotel or HQ where 10 m between roof and ground floor is impossible, place the whips on the lower floors away from the roof face, maximise the physical gap, and keep the ten antennas off the Yagi's back lobe.

Step 2: Route the 10m Outdoor and 5m Indoor Feeds, Choose a Longer Outdoor Cable

The Yagi connects to the chassis by the included 10 m outdoor low-loss coax, and the whip connects by the separate 5 m indoor feed; keeping the two runs separate avoids a single long shared length and lets each match its own distance. Every metre spends signal, so route the shortest practical path and avoid sharp bends that compress the shield.

Sealed entry and tidy routing for both feeds

Pass the 10 m outdoor coax through a sealed grommet or a small angled drill hole with a drip loop below the entry so rain runs away rather than down the wire. The 5 m indoor feed runs from the chassis MS port to the first whip inside; keep both feeds clear of mains wiring, TV aerial coax and metal ducting, which can inject noise, and avoid tight coils beside the chassis where the bundle distorts the field. Terminate both connectors firmly; a loose BS connection is the most common dark-LED cause on an enterprise install.

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

Where the Yagi mount sits more than 10 m from the proposed chassis room, order the 20, 30, 40 or 50 m outdoor cable upgrade instead of splicing the standard lead; a spliced joint adds mismatch and water risk, and a longer low-loss run preserves the signal better than a join. One Vodafone customer in Wales took the 50 m roof run to reach the comms room and reported the signal went solid across the entire 2000 m² production area afterwards. The 5 m indoor feed stays as supplied between chassis and first whip; when you add the second through tenth antennas, the extra runs come from the splitter branches, not from extending the BS lead.

Step 3: Chassis Placement and the BS versus MS Ports

The compact chassis sits in a comms cupboard, server room, under-counter space or on a shelf in the covered space, kept ventilated and away from direct heat. The two ports are labelled, and swapping them inverts the loop and causes oscillation, so match lead to port on the first attempt.

Why a port swap loops fastest at enterprise output

If the Yagi feed plugs into MS and the whip trunk into BS, the interior whips radiate straight back into the directional panel, the chassis feeds its own output, and automatic gain control drives the stage toward oscillation until the LED flickers and the zones drop. The 27 dBm level means a swapped pair feeds back harder than a 20 dBm box; the fix is to swap the two leads. Once BS carries the mast donor and MS carries the indoor whips, the two sides face opposite environments and the loop stays open. Keep each whip upright on a shelf or stand, not pressed against the Yagi feed, a steel cabinet or a concrete pillar.

Where the whips radiate best across 2000m²

The 3 dBi whip radiates the amplified field across open-plan HQ floors, hotel corridors, warehouse bays, reception and mall aisles; place the first whip centrally rather than tucked behind a filing cabinet, where furniture and shelving mask the reach. Coverage is rated to 2000 m² for a headquarters, multi-floor office, hotel, warehouse, mall or industrial unit, and the 27 dBm field spreads across the ten zones; a far bay that reads light is the reason to add another antenna through the splitter stack rather than moving the whip endlessly.

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

The chassis runs from the included UK adapter converting AC 100-240V to DC 5V, and the order matters: mount and connect both antennas before powering on, so the gain stage does not latch into a self-fed loop the moment it wakes.

Correct power-on sequence and fine-aim after boot

First the Yagi is fixed and aimed and the 10 m feed reaches the BS port; second the 5 m indoor feed connects the MS port to the whip or splitter trunk; only then the 5V DC adapter receives mains power. Powering up before the MS side is connected lets the chassis radiate into an open port and can trigger oscillation. Wait ten seconds after power, then fine-rotate the Yagi a few degrees while a helper watches the phone reading at the whips, and lock the clamp at the peak before commissioning the rest of the zones and the splitter expansion.

Reading the status LEDs on an enterprise install

A steady bright LED on the chassis confirms both Band 20 and Band 1 are locked and the gain stage has settled; a flickering or climbing pattern points to oscillation, a port swap or an overloaded donor, while a permanently dark LED with power present means a loose BS lead, a blown adapter fuse or a Yagi aimed at sky rather than a mast. As the outside signal swings with weather and traffic, the LED may dim momentarily as the gain rebalances, which is normal; keep the adapter earthed and add the 18KA surge protector where lightning exposure on the roof mast justifies it.

The 18KA surge protector on the rooftop mast run

For a tall rooftop mast, an exposed gable or a rural industrial park prone to storms, the optional 18KA lightning surge protector sits on the outdoor coax between the Yagi and the chassis, diverting a static or lightning spike away from the indoor electronics. It does not improve signal and is not required on a sheltered mid-wall install, but it protects the long outdoor run and the chassis where the panel stands highest on an exposed enterprise roof.

Splitter Expansion: Ten Indoor Antennas Across Floors, Wings and Aisles

The CW2000 page states, verbatim, "Expandable coverage by adding indoor antenna, splitter, cable if the outside signal is strong." That condition matters: a weak donor cannot afford split loss, and only a strong outside reading funds a ten-antenna layout.

How stacked multi-way splitters reach ten zones on 2000m²

When the aimed Yagi reads strong, fit the first multi-way splitter on the MS side after the chassis, run its branches to a second distribution layer for additional whips, place a second whip in reception or open plan, a third and fourth on the next floors or corridor wings, a fifth and sixth in the warehouse bays, a seventh and eighth in the hotel or mall aisles, and a ninth and tenth in the far offices or outlying areas of the rated space, and balance every branch. Each division spends radiated power, but the 27 dBm output and the 70/75 dB gain have the headroom to feed ten antennas across the premises; the second through tenth whips only reach their zones while the donor stays strong. Keep every whip separated from the Yagi and from each other so none feeds the next, and measure each zone before committing the extra cables and splitters.

When not to split to ten

A donor between -100 and -112 dBm already strains a single whip even with the higher gain, and dividing the field ten ways produces ten lighter readings rather than ten solid ones; in that case improve the Yagi aim first, check the roof position, or step to a dedicated multi-access point indoor system rather than dividing a weak signal ten times. Splitting is an expansion of a strong baseline, never a rescue for a faint donor.

The 200-User Test: 4G Data and 3G Calls Across 2000m²

The CW2000 supports up to 200 simultaneous handsets across 2000 m²; the acceptance test checks that HQ floors, hotel corridors, warehouse bays, reception and mall aisles all hold a 4G session and a 3G call at once rather than one phone beside the whip.

How to stage the acceptance test

Place mixed handsets on EE, O2, Vodafone, Three, giffgaff, Tesco, Sky, Smarty and Lebara SIMs across the floors, wings, desks, reception, warehouse and aisles; start a data session on one group and a voice call on another, hold both for a minute, then walk the reading around the space. Record the bar count before fitting, after fitting near the whip, and after fitting at the far bay, corridor or aisle; a Devon headquarters that went from one bar to five on EE across all 2000 m², a Yorkshire hotel whose guest calls stopped dropping on every floor with ten indoor antennas, and a Cornwall office whose video calls held for 200 users match the reported pattern. With 200 users in an HQ, hotel, mall or warehouse, stagger sessions so the gain stage balances the load rather than piling every handset on one whip.

Expected coverage by enterprise space

CW2000 Against the Range: Seven Decibels More Output, Ten Antennas

The Boost4U range splits by tuned band, gain, output, area and users, and choosing the wrong model leaves either a service gap or unused budget.

The CW1000 repeats the same Band 20+1 services at the same 70/75 dB gain tier on a 20 dBm output for 1000 m² and 100 users with four indoor antennas; the CW2000 keeps the bands and gain but raises the output by seven decibels, about five times the radiated power, spreads over 2000 m² for 200 handsets, and supports ten antennas through the stacked splitters. The CG2000 keeps O2/Vodafone 4G plus a 2G circuit call but leaves the all-network 3G layer absent; the CD2000 keeps 4G families but carries neither 3G fallback nor a dedicated call band. Pick CW2000 for 3G redundancy across EE, O2, Vodafone and Three across a multi-floor enterprise premises.

Troubleshooting: Oscillation, No Signal and the LED Read-Out

Oscillation: looped field and flickering LED

The symptom is a flickering or climbing LED, a reading strong beside the whip but a step away falling, and dropped sessions despite power. Causes are a BS/MS port swap, a whip too close to the Yagi feed, a ninth or tenth whip placed in the Yagi's back lobe, or insufficient 10 m isolation letting the high-output chassis feed itself. Fix the ports, increase the separation, space the ten whips around the zones, and let gain settle rather than driving into the loop.

No signal at all: dark LED, loose leads, or Yagi in the sky

A dark LED with the adapter live points to a loose BS connector, a blown adapter fuse, or the Yagi aimed at sky or a roof unit rather than the serving mast. Reseat both connectors, try another socket, rotate the panel a few degrees while a helper watches the phone, and verify a reading exists outside first; if the phone reads zero on the roof, the booster cannot recover a block absent from the tower.

Weak far zone, dead valley and mains noise

A lighter zone comes from the whips clustered on one floor; spread them central across floors, wings and aisles, or split to a second through tenth antenna only on a strong donor. A dead valley below the decode floor needs a better mast bearing or a fixed multi-array system rather than another whip indoors. Hum following the mains points to the outdoor coax running beside the power loom; separate the feed and re-check.
