Answer up front: for a mixed-network three-bedroom house, large flat, small office or cafe that needs EE, O2, Vodafone and Three 4G data plus a universal 3G fallback across 250m² for 25 users at ≥17 dBm with up to 3 indoor antennas, the CW250 at £295.00 is the pick; it pairs Band 20 at 800 MHz data with Band 1 at 2100 MHz 3G UMTS data, voice and SMS on every network, outputs ≥17 dBm — a +7 dBm step over the CW200 — behind a ≤5 dB noise figure, and ships the 5 dBi omni, 3 dBi whip, 10m outdoor plus 5m indoor coax and UK plug. For a two-bedroom flat at 200m² for 20 users with 2 antenna zones, the CW200 at £205.99 saves £89.01 on the same universal Band 20+1 at ≥10 dBm. For an O2/Vodafone-only household relying on legacy 2G calling, the CG250 at £295.00 tunes Band 8 instead of Band 1.

The CW250-versus-CW200 gap is a scale, output and antenna step, not a network change: both carry Band 20+1 and universal 3G, but the CW250 adds +50m² (250 against 200), +5 users (25 against 20), the +7 dBm output step (≥17 against ≥10, roughly five times power) and a third indoor antenna zone on a 3-way splitter. The CW250-versus-CG250 gap is a band choice at the same £295.00, same 250m², same 25 users and same gain class: Band 1 universal 3G versus Band 8 O2/Vodafone 2G, with the CW250's higher output feeding three rooms.

This page compares the three Boost4U chassis side by side rather than in a roundup: the CW250 at £295.00, the CW200 at £205.99 and the CG250 at £295.00. It separates the shared Band 20 data layer from the two different choices a buyer must make — how many rooms, how many devices and how much output (CW250 vs CW200) and which fallback band (Band 1 universal 3G vs Band 8 O2/Vodafone 2G) — and gives a decision tree so the choice follows floor plan, headcount, output need, SIM mix and whether VoLTE covers calls today.

All three are UKCA and CE certified, Ofcom licence-exempt, ship free within the UK on 1 to 2 day handling plus 10 to 15 day transit, and carry a 365-day mail return window. None carries 5G; the CW250 and CW200 carry Band 1 3G, while the CG250 carries Band 8 2G instead. All run from the AC 100–240V to DC 5V UK Type plug. The rest of this page numbers every band, £89.01 step and spec before you order.

Before the tables, three rules keep the comparison honest. First, Band 20 at 800 MHz (uplink 832–862 MHz, downlink 791–821 MHz) is shared by all three and carries EE, O2, Vodafone and Three 4G data, so data capability is not the deciding factor between CW250 and CW200; the deciding factor is scale and output. Second, the CW250 and CW200 add Band 1 at 2100 MHz (uplink 1930–1990 MHz, downlink 2110–2180 MHz) for 3G UMTS data, voice and SMS on every network, while the CG250 instead tunes Band 8 at 900 MHz for O2/Vodafone 2G. Third, between CW250 and CG250 the price, area, users and gain match, so that tie decides by fallback band and output; between CW250 and CW200 the band plan matches and the £89.01 decides by area, users, output and antenna zones.

Because the CW250 and CW200 share the Band 20+1 plan, this comparison never turns CW250 against CW200 on network coverage; it turns on whether the home fills 200m² for 20 users or 250m² for 25, and whether a third room needs the higher ≥17 dBm output. A two-bedroom flat cannot use the extra 50m² and five users, so the CW200's £89.01 saving is rational; a three-bedroom house with a spare bedroom, home office and cafe-style footfall needs the CW250's larger area, higher output and third antenna zone to hold one universal fallback.

Coverage figures assume reasonable donor signal outside and sensible antenna separation; the rated 250m² covers a three-bedroom house or large flat, and 200m² covers a two-bedroom flat or small home. On a strong −70 to −90 dBm donor the CW250 can feed up to 3 indoor antennas via a 3-way splitter while the CW200 feeds up to 2 via a 2-way splitter; a weak −97 to −105 dBm donor uses the optional Yagi aimed at the nearest mast. The tables below compare specs, the £89.01 step and day-one versus five-year cost before the decision tree.

Read the band row before the price row: CW250 and CW200 share Band 1 universal 3G, CG250 keeps Band 8 O2/Vodafone 2G; then read the scale and output rows, where CW250 adds 50m², five users, the ≥17 dBm step and a third antenna zone over CW200, and matches CG250 on scale while differing only in fallback band and output.

The £89.01 between CW200 and CW250 buys area, users, output and a third antenna zone, never a new network; the £0.00 tie between CW250 and CG250 buys a different fallback band and the higher output rather than more scale. A buyer who stretches CW200 to a third room pays for a larger tier later, and a CG250 buyer who later needs EE/Three fallback pays a Band 1 unit on top.

The CW250 and CW200 share an identical band plan: Band 20 at 800 MHz for EE, O2, Vodafone and Three 4G data, plus Band 1 at 2100 MHz for 3G UMTS data, voice and SMS on every network. No network one covers, the other misses; the £89.01 difference exists entirely to serve more space, more devices, more output and a third indoor zone.

CW200: the 200m²/20-user two-room unit at £205.99

The CW200 reaches 200m² (2,153 ft²) for up to 20 users at ≥60 dB uplink / ≥65 dB downlink gain, ≥10 dBm output, the 5 dBi omni, 3 dBi whip and 10m outdoor plus 5m indoor coax, with up to 2 indoor antennas on a 2-way splitter. It suits a two-bedroom flat or small home where the active devices sit around two whips. Buyers here should not pay for a third room they never occupy.

CW250: the 250m²/25-user flagship at £295.00

The CW250 reaches 250m² (2,691 ft²) for up to 25 users at the same ≥60/≥65 dB gain, but outputs ≥17 dBm — a +7 dBm step over the CW200's ≥10 dBm, roughly five times the transmitted power — and supports up to 3 indoor antennas on a 3-way splitter. The higher output spreads the universal Band 1 signal into a spare bedroom, home office or cafe corner that a 2-antenna ≥10 dBm unit reaches weakly, and the extra five-user headroom keeps a small crew from crowding one cell.

The £89.01 step decides by floor plan and output, not by network

Because coverage and fallback are identical, the CW200-versus-CW250 choice is a pure sizing and power question: measure the rooms one whip zone must serve, count active devices, and only pay £89.01 when the home genuinely fills 250m², approaches 25 connections and needs a third antenna fed by ≥17 dBm. A two-bedroom buyer on CW250 overpays for unused scale; a three-bedroom buyer on CW200 gets a weak far room and congestion at the third zone.

The CW250 and CG250 tie on price, area, users and gain, differing in the fallback band and the output class, because both share Band 20 for EE, O2, Vodafone and Three 4G data.

CW250 Band 1: universal 3G for all four networks at higher output

The CW250 tunes Band 1 at 2100 MHz (uplink 1930–1990 MHz, downlink 2110–2180 MHz). On EE, O2, Vodafone and Three this provides a 3G UMTS data, voice and SMS fallback where 4G alone weakens, including MVNOs riding those networks, and the ≥17 dBm output spreads that fallback across three indoor zones. It does not tune Band 8 O2/Vodafone 2G; a legacy 2G-only O2/Vodafone handset that cannot fall to 3G relies on VoLTE or its native network rather than a boosted 2G channel.

CG250 Band 8: O2/Vodafone 2G only at lower output

The CG250 tunes Band 8 at 900 MHz instead, which carries O2 and Vodafone 2G voice calls and SMS, and 900 MHz reaches deeper through masonry than higher bands. On EE and Three it provides Band 20 data only with no boosted call fallback; it never tunes Band 1 3G, and it ships at the ≥10 dBm output class rather than the CW250's ≥17 dBm. The CG250 is the right box when the household SIMs are O2/Vodafone-led and legacy 2G calling matters to those two networks only.

The £0.00 tie decides by call path and output, not by scale

Because price, coverage, users and gain are identical, the CW250-versus-CG250 choice is a pure fallback question: mixed-network home needing universal 3G across three zones = CW250; O2/Vodafone-only household needing legacy 2G = CG250; mixed where both Band 1 3G and O2/Vodafone 2G matter = no single chassis solves both, and a band-specific second unit is required rather than forcing one box.

Walk the branches top to bottom and stop at the first yes.

Branch 1 — Does the space fill roughly 250m² across three rooms or a small office, with up to 25 active phones, tablets and laptops?

Yes: scale belongs on the flagship CW tier rather than the 200m² CW200; move to Branch 2 for the band question. No: under 200m² for 20 users, jump to Branch 4.

Branch 2 — Do the household SIMs mix EE, O2, Vodafone and Three, or do guests/devices change network between rooms and zones?

Yes: the universal Band 1 3G layer and the ≥17 dBm output for a third zone matter, so choose the CW250 at £295.00, Band 20+1, 250m², 25 users, ≥17 dBm, 3 antenna zones. No and all SIMs are one network: move to Branch 3.

Branch 3 — Are all SIMs O2/Vodafone-led and do the handsets rely on legacy 2G rather than VoLTE or 3G?

Yes: CG250 at £295.00, Band 20+8, O2/Vodafone 2G calls, accept EE/Three data-only at ≥10 dBm. No (modern VoLTE phones, mixed networks, rural mast swing, need a third zone): stay with the CW250's Band 1 universal fallback.

Branch 4 — Is the job a two-bedroom flat or small home under 200m² for about 20 users on a mixed-network Band 20+1 plan with two antenna zones?

Yes: CW200 at £205.99, same universal Band 1 3G on the smaller scale at ≥10 dBm, save £89.01. No and the space grows beyond 200m²: return to Branch 1 for the CW250.

Branch 5 — Do you need 5G, a multi-floor whole mansion beyond 250m², more than 25 users, or both Band 1 3G and Band 8 2G at once?

Yes: a £205.99 or £295.00 single-fallback room unit is undersized or band-wrong; choose a larger multi-antenna or band-specific system. No and the space fits 250m²: return to Branch 1, 3 or 4 and order the matched unit.

Day one, the CW250 and CG250 tie at £295.00; the CW200 sits £89.01 below at £205.99. The five-year total separates a correctly matched flagship from a late step-up or second band.

The CW200 buyer who adds a third bedroom or home office must step up a tier rather than stretch a 2-antenna ≥10 dBm box; the CG250 buyer who later adds EE or Three devices pays a Band 1 unit on top of the £295.00 already spent. Only the correctly matched single CW250, CW200 or CG250 closes the job day one; over-buying CW250 for two rooms wastes £89.01, while under-buying CW200 for a three-bedroom home forces a second purchase.

The CW250 box at £295.00 holds the 450g booster (170×110×30mm), the 5 dBi omni outdoor aerial, the 3 dBi whip indoor antenna, the UK power adapter, the 10m outdoor low-loss coax, the 5m indoor coax, a mounting bracket and a quick start guide; paid variants are the high-gain Yagi, 20/30/40/50m external cable and 18KA protector. On a strong −70 to −90 dBm donor, a 3-way splitter and extra coax feed up to 3 indoor antennas for spare rooms; a weak −97 to −105 dBm donor uses the optional Yagi aimed at the nearest mast. The CW200 box mirrors the cable stack at £205.99 with a 2-way splitter, and the CG250 box mirrors the cable stack for Band 8.

Basic setup takes 10 to 15 minutes without tools: mount the omni with a clear mast view, keep the whip a sensible distance inside, run the outdoor and indoor coax, power from the UK plug, and read steady green before testing. The expansion note reads "Expandable coverage by adding indoor antenna, splitter, cable if the outside signal is strong."

All three carry UKCA, CE and RoHS, are Ofcom licence-exempt, ship free within the UK (handling 1–2 days, transit 10–15 days), and carry a 365-day mail return window. The £295.00 CW250 price is valid to 2027-10-21, InStock NewCondition, and ships to GB, DE, FR, IT, ES, NL, BE, AT, SE, DK, FI, IE, PT, PL and CZ; the CW200 at £205.99 and CG250 at £295.00 follow the same shipping and return terms.

Three-bedroom house, large flat, small office or cafe filling 250m², up to 25 mixed-network devices, universal 3G across EE/O2/Vodafone/Three with a third antenna zone fed by ≥17 dBm: CW250 at £295.00, Band 20+1, the only chassis that pairs universal Band 1 with this scale, output and 3-way expansion.

Two-bedroom flat or small home under 200m² for 20 mixed-network users with two antenna zones: CW200 at £205.99, Band 20+1, save the £89.01 you never use.

O2/Vodafone-only household on legacy 2G at 250m²: CG250 at £295.00, Band 20+8, accept EE/Three data-only at ≥10 dBm.

Quick verdict: the CW250 and CW200 speak the same universal Band 1 language, with the £89.01 difference buying 250m², 25 users, a +7 dBm output step and a third antenna zone rather than a new network; the CW250 and CG250 cost the same and match on scale, so there the Band 1 versus Band 8 call path decides — pick CW250 for mixed-network 3G at high output, CW200 for two rooms, CG250 for O2/Vodafone 2G only.
