    Pros & Cons

    Pros

    • The only Band 20+8 combo at 250m²: O2/Vodafone users get BOTH 4G data on Band 20 and 2G voice calls/SMS on Band 8 from one device, at £295.00.
    • ≥60 dB uplink / ≥65 dB downlink gain and ≥17 dBm high output with ≤5 dB noise figure drive more power through walls, lifting weak rural O2/Vodafone signal over 250m².
    • Band 8 900MHz has better in-building penetration than pure-data boosters, so calls stay connected where data-only units drop off.
    • Plug-and-play 10–15 minute setup, no engineer visit, no Ofcom licence, no monthly fee and no new SIM contract.
    • O2/Vodafone family members keep 4G data and voice together; giffgaff, Sky, Talkmobile, Lyca, Tesco networked 4G boosted on Band 20.
    • Supplied complete with 5 dBi omni, 3 dBi whip, 10 m outdoor + 5 m indoor coax and UK mains adapter; Yagi aerial and 20–50m outdoor cable upgrades available.
    • Covers up to 250 m² for up to 25 users in a three-bedroom home, medium flat, small office, cafe or holiday let; up to 3 indoor antennas extend multi-room zones.
    • UKCA/CE/RoHS certified and Ofcom licence-exempt; 365-day money-back guarantee and free shipping to 15 European countries.

    Cons

    • Coverage tops out at 250 m² — it will not cover a large house on several floors or many rooms without additional antennas via splitter and strong donor.
    • EE 4G data passes on Band 20 but EE 2G voice (Band 3 1800MHz) is NOT boosted; EE call fallback users need a Band 20+3 unit instead.
    • No 3G (Band 1 2100MHz) and no 5G on any band; calls rely on 2G Band 8 or 4G VoLTE where offered.
    • It cannot solve a site with no donor signal outside; it amplifies the donor it receives rather than creating signal.
    • The supplied 5 dBi omni may need the paid high-gain Yagi upgrade at -97 to -105 dBm fringe signal behind a ridge or other buildings.
    • The included 10 m cable may need the 20/30/40/50 m upgrade for a remote roof or outbuilding.
    • Outdoor omni and indoor whip need 10 m vertical separation to prevent self-oscillation, which a compact layout may struggle to fit.
    • Free delivery takes 10–15 working days after 1–2 days handling — not next-day; the unit has no LCD meter and the 25-user cap suits a home or small business, not an enterprise floor.

    Custom Your Solution — Expand to Three Zones

    Planning a custom CG250 solution adding indoor antennas, a splitter and extra cable to extend coverage to three zones when outside signal is strong

    Expandable coverage by adding indoor antenna, splitter, cable if the outside signal is strong.

    1. Check the outdoor donor. When outside signal is strong (roughly -70 to -90 dBm, 3–4+ bars on the roof), indoor antennas can split and extend coverage; a weak donor does not multiply by splitting.
    2. Map the zones. Plan rooms or corners beyond the main whip's reach; feed up to 3 indoor antennas from the booster through a 2-way/3-way passive splitter.
    3. Add indoor antennas + splitter + cable. The CG250 supports up to 3 indoor antennas total; add extra whips in far rooms and run extra coaxial cable to each zone from the splitter for even coverage.
    4. Choose cable length. The 10m outdoor standard cable suits a normal roof; the 5m indoor cable feeds the main whip; add 20m +£20, 30m +£30, 40m +£40 or 50m +£50 for a remote roof, outbuilding or long indoor run to a remote antenna.
    5. Add protection. A surge protector (+£20) shields the unit on an exposed roof mount; combinations reach up to £415.00.
    6. Keep separation. Maintain the 10m vertical gap between outdoor omni and indoor whips to prevent feedback, and test bars in each zone before fixing.

    Frequently Asked Questions — Real UK O2/Vodafone Dual-Band 4G+Voice User Questions

    How does the CG250 differ from the CG200 (200m², 20 users, ≥10dBm) and the CD250 (Band 20+3)?

    The CG200 carries the same Band 20+8 combo but covers 200m² for 20 users at ≥10dBm output; the CG250 adds +50m², +5 users and a much higher ≥17dBm output (+7dB ≈ 5× power) and capacity for 3 indoor antennas via splitter. The CD250 pairs Band 20 with Band 3 (1800MHz) at the same £295.00 price to boost EE 4G plus EE 2G voice, while O2/Vodafone users get 4G data only. Choose the CG250 for O2/Vodafone data plus voice across 250m²; choose the smaller CG200 for 200m²; choose the CD250 if EE voice matters.

    What is the difference between Band 20 (800MHz) data and Band 8 (900MHz) voice on the CG250?

    Band 20 (800 MHz) carries O2, Vodafone and Three 4G data over long rural distances; Band 8 (900 MHz) carries O2/Vodafone 2G voice calls and SMS and penetrates walls and stone better than higher bands. The CG250 amplifies both at once, so an O2/Vodafone phone keeps its data session and ordinary calls connected where a data-only booster leaves calls dropping.

    How much area does "up to 250m²" cover, and why is it not a whole-house booster?

    Up to 250 m² (2,691 ft²) covers a three-bedroom home, medium flat, small office, cafe or holiday let. The ≥17 dBm high output and the whip are sized for that footprint; a larger multi-floor house can be extended to up to 3 indoor antennas via splitter only when the outdoor donor is strong.

    How do 25 simultaneous users work on the CG250?

    The CG250 supports up to 25 phones or data devices connected at the same time, sharing boosted Band 20 data and Band 8 voice capacity — a family home, small office or cafe. Beyond 25 active devices the shared RF capacity thins out; it is connected capacity, not a guaranteed 25 fast-speed lines at once.

    What do ≥60dB uplink, ≥65dB downlink gain and the ≥17dBm output mean?

    Gain in dB measures how much the amplifier strengthens the incoming signal: ≥60 dB uplink lifts the phone's signal back to the mast and ≥65 dB downlink lifts the mast's signal to the phone. Output in dBm measures final radiated strength; ≥17 dBm is a high output — +7dB over the CG200’s ≥10dBm, roughly 5× power — that spreads boosted signal across the full 250 m² footprint through walls, within Ofcom licence-exempt limits.

    Does the CG250 boost EE calls?

    EE 4G data passes through Band 20, but EE 2G voice rides Band 3 (1800MHz), which the CG250 does not cover, so EE call fallback is not boosted. If you need both EE data and EE voice, the Band 20+3 unit is the correct choice; the CG250 is purpose-built for O2/Vodafone data plus voice.

    Should I use the included 5dBi omni or the Yagi directional upgrade?

    The supplied 5 dBi omni works with a clear mounting spot showing 1–2+ bars. For weak -97 to -105 dBm fringe signal behind a ridge or other buildings, the paid high-gain Yagi aerial aims at the nearest mast and pulls a cleaner donor that the ≥60/65 dB gain then amplifies. Start with the omni and add the Yagi only if bars stay weak.

    How much outdoor donor signal does the CG250 need before it can work?

    At least 1–2 bars of usable outdoor signal on Band 20 and/or Band 8 at the omni mounting point, checked with a phone on the roof or wall. A booster amplifies the donor it receives; it cannot create signal where none exists outside, and adding indoor antennas via splitter only helps when outside signal is already strong.

    What does the 365-day return policy cover, and how long does delivery take?

    The CG250 carries a 365-day money-back guarantee: if it does not work for your location, return it by mail within 365 days for a refund; return shipping is deducted from the refund (ReturnShippingFees), so it is not a free-return label. Standard delivery is free: handling takes 1–2 working days and UK transit 10–15 working days, so it is not next-day, and the same policy covers 15 European countries (GB, DE, FR, IT, ES, NL, BE, AT, SE, DK, FI, IE, PT, PL, CZ).

    Does the CG250 support VoLTE, and will it boost 5G or 3G?

    The CG250 boosts 4G LTE data (Band 20) and 2G voice/SMS (Band 8); calls over 4G work when the handset and network offer VoLTE. It does not boost 5G NR on any band and it does not boost 3G UMTS Band 1 (2100 MHz), so a device stuck on 3G fallback will not be helped. If 5G speed or 3G fallback is the main requirement, a different unit on those bands is needed.

    How It Works


    how 4G LTE Mobile Signal Booster O2 Signal Booster Vodafone Signal Booster Giffgaff Signal Booster Sky Mobile Signal Booster Indoor Coverage UK Mobile Network work for home office

    1

    Receives signal
    The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster

    2

    Boosts signal
    The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.

    3

    Broadcasts signal
    Your devices get increased cell reception, and calls and data are fed through the booster back to the network.
