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.

How It Works
The C1000 uses a three-stage amplification system. The 12 dBi outdoor Yagi antenna captures the weak 4G Band 20 signal from the nearest mast. The booster unit amplifies this signal by up to 80 dB with automatic gain control to prevent oscillation. The 10 dBi indoor antenna then rebroadcasts the amplified signal throughout the 1000 m² coverage area. Every phone in range connects to the boosted signal automatically — no WiFi, no apps, no network configuration.
Installation Guide
- Signal survey: Walk around the exterior of your property with a phone in 4G-only mode. Find the wall with the strongest signal — this is where the outdoor antenna goes.
- Mount outdoor antenna: Fix the 12 dBi Yagi antenna to an exterior wall, pole or chimney, pointing toward the nearest mobile mast. Ensure at least 5 m vertical separation from the indoor antenna.
- Run cable: Route the 20 m low-loss cable from the outdoor antenna to the booster location inside. Avoid running near fluorescent lights or electrical equipment.
- Mount indoor antenna: Place the 10 dBi panel antenna centrally in the area needing coverage, at least 2 m above floor level.
- Connect and power: Connect cables to the booster unit, plug in the power adapter. Wait 30 seconds for automatic calibration.
- Test: Check 4G signal bars and run a speed test on your phone. Adjust antenna position if needed.

The C1000 covers up to 1,000 m² of indoor space, suitable for 6–10 bedroom houses, large offices, pubs, restaurants, hotels and warehouses. Actual coverage depends on outdoor signal strength and building materials.
Will the C1000 work with my network?
Yes. The C1000 amplifies Band 20 (800 MHz), which is used by all four UK networks (EE, O2, Vodafone, Three) and their MVNOs. Every phone in the building benefits simultaneously.
How much does the C1000 cost?
The C1000 is priced at £535.00 GBP with free UK shipping. There are no ongoing fees, subscriptions or network charges. A 365-day money-back guarantee is included.
Is the C1000 legal to use in the UK?
Yes. The C1000 is Ofcom licence-exempt and UKCA/CE certified. It meets all technical requirements for legal use in the UK, including automatic gain control and output power limits.
Do I need an engineer to install it?
