Custom your solution
Expandable coverage by adding indoor antenna if the outside signal is strong.
How It Works
1
The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster
2
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.
3
Your devices get increased cell reception, and calls and data are fed through the booster back to the network.
Get stronger signal
Normal Cell Coverage
Dropped calls and slow data are generally caused by three things: distance from a cell tower, building materials in your home or office, or obstruction from tall objects such as trees, topography, and buildings.
Signal Coverage with our booster
Signal boosters increase cell signal by collecting signals with a powerful antenna, delivering those signals to the booster, amplifying the cell signals so your devices receive them, and delivering your device's boosted signals back to the cell tower.Installation
- Connect the indoor antenna to the MS port.
- Connect the outdoor antenna to the BS Port.
- Install the outdoor antenna and keep a minimum vertical distance of 10 meters from the indoor antenna.
- Point the outdoor antenna to the direction where you know there is possibly a higher signal strength from the base station.
- Power on the booster and check the signal strength.
- Adjust the outdoor antenna until you get the best signal strength.
IMPORTANT NOTE:
DO NOT POWER ON THE DEVICE UNTIL YOU HAVE COMPLETED THIS SETUP.

Pros & Cons
| Pros | Cons |
|---|---|
| ✅ Works with ALL four major UK networks (EE, O2, Vodafone, Three) | ❌ 4G LTE only — does not boost 2G/3G voice on 900 MHz |
| ✅ 200 m² coverage suits most UK family homes and small offices | ❌ Requires VoLTE-enabled phone and plan for calls (most modern phones support this) |
| ✅ 70 dB gain — highest in its price tier | ❌ Requires at least 1–2 bars of outdoor 4G signal |
| ✅ Up to 50+ Mbps download speeds in testing | ❌ Outdoor antenna must be mounted on exterior wall or roof |
| ✅ 365-day money-back guarantee and lifetime support | ❌ Not suitable for buildings over 200 m² (see C100 for 300 m²) |
| ✅ Low power consumption (≤12 W) — costs ~£15/year | ❌ Cable length fixed at 10 m; longer runs require upgrade |
| ✅ Licence-exempt under Ofcom regulations | ❌ £169.99 — more expensive than voice-only boosters |
How It Works
The C200 operates on a three-stage relay principle optimised for 4G LTE Band 20. The outdoor antenna captures the weak 800 MHz signal from the nearest mast and passes it via coaxial cable to the booster unit. The booster amplifies the signal by up to 70 dB using low-noise amplification (≤4 dB noise figure) and rebroadcasts it indoors through the panel antenna, delivering fast 4G data and clear VoLTE calls throughout 200 m².
The system is bidirectional: it also amplifies the signal your phone sends back to the mast, ensuring both upload and download speeds improve. Automatic gain control (AGC) prevents oscillation and adjusts output based on incoming signal strength, maintaining stable performance even as network conditions change.
Installation Steps
- Find the strongest outdoor 4G signal using your phone's signal meter or the Network Cell Info app.
- Mount the outdoor antenna on an exterior wall, pole or roof, pointing toward the nearest mast.
- Run the 10 m coaxial cable from the outdoor antenna to the booster unit indoors.
- Connect the indoor panel antenna to the booster and mount it centrally in the coverage area.
- Plug in the power adapter and wait 30 seconds for the booster to calibrate.
- Test 4G speeds using speedtest.net — expect 10–50+ Mbps where previously 0–5 Mbps.
Frequently Asked Questions
1. Will the C200 work with my network?
The C200 works with all four major UK networks — EE, O2, Vodafone and Three — on their Band 20 (800 MHz) 4G LTE frequency, plus all their MVNOs including BT Mobile, Plusnet, giffgaff, Sky Mobile, Tesco Mobile, Lebara, VOXI, iD Mobile and SMARTY. It is the most network-compatible booster in the Boost4U range.
2. Does the C200 boost 4G internet speed?
Yes. The C200 is specifically designed to amplify 4G LTE data on Band 20 (800 MHz). In real-world testing, users report download speeds increasing from 1–5 Mbps to 15–50+ Mbps, depending on outdoor signal strength and network congestion. It also supports VoLTE for high-quality voice calls over 4G.
3. How big an area does the C200 cover?
The C200 covers up to 200 m² (approximately 2,153 sq ft) under ideal conditions with a strong outdoor signal. Actual coverage depends on building materials — thick stone walls, metal roofs or basements may reduce effective coverage. For larger properties up to 300 m², the Boost4U C100 model offers greater coverage.
4. Is the C200 legal in the UK?
Yes. The C200 is a licence-exempt mobile repeater under Ofcom regulations, provided it is installed correctly and does not cause interference to the mobile network. Ofcom legalised the use of certain mobile repeaters in 2018, and the C200 meets all technical requirements for exemption including automatic gain control and power limits.
5. Do I need an engineer to install it?
No. The C200 is designed for DIY installation. The complete kit includes all hardware, and most customers install it in 20–25 minutes using only a drill and screwdriver. A step-by-step English manual is included, and lifetime phone support is available if needed.
6. What if I have no outdoor 4G signal?
A booster cannot create signal where none exists. The C200 requires at least 1–2 bars of usable Band 20 4G signal outdoors to amplify. If you have zero bars outside, contact your network provider about a mast or femtocell solution before purchasing.
7. Will it improve my VoLTE calls?
Yes. By amplifying the 4G LTE signal, the C200 improves VoLTE (Voice over LTE) call quality and reliability. If your phone and network support VoLTE (most modern phones and all UK networks do), calls will be clearer and more stable. If VoLTE is not available, calls may fall back to 2G/3G which the C200 does not amplify.
8. How much does it cost to run?
The C200 consumes ≤12 W, which costs approximately £12–18 per year in electricity at current UK rates. It is designed to run continuously 24/7 and has no ongoing subscription fees or network charges.
9. Can I use it in a listed building or rented flat?
The indoor unit is small (180 × 120 mm) and can be placed on a shelf or mounted with adhesive strips, requiring no structural changes. The outdoor antenna may require landlord permission if you rent. For listed buildings, consult your local conservation officer before drilling exterior walls.
10. What is the return policy if it doesn't work?
Boost4U offers a 365-day money-back guarantee. If the C200 does not improve your 4G signal, you can return it within 365 days for a full refund, minus shipping costs. The company also provides lifetime technical support to help optimise installation and antenna placement.
