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.

- Monthly: 0.48 × 30 = 14.4 kWh → £3.89/month
- Annually: 0.48 × 365 = 175.2 kWh → £47.30/year
Frequently Asked Questions
Will the G1000 improve my 4G internet speed?
No. The G1000 is a Band 8 900 MHz 2G/3G booster for calls and SMS only. It does not boost 4G LTE or 5G data. For 4G data, consider the Boost4U C1000 (£535).
Which networks does the G1000 work with?
The G1000 works with O2, Vodafone and their MVNOs: giffgaff, Sky Mobile, Lebara, Lycamobile and Tesco Mobile. It does not support EE or Three, which use different frequency bands for calls.
How big an area does the G1000 cover?
The G1000 covers up to 1000 m² with proper installation — equivalent to a 7+ bedroom house, a large pub, or a small office building. Actual coverage depends on outdoor signal strength, building materials and antenna placement.
Is the G1000 legal in the UK?
Yes. The G1000 is Ofcom licence-exempt with UKCA/CE certification. Its output power (23 dBm) is within Ofcom's 27 dBm limit for 900 MHz, and it includes automatic gain control to prevent interference. Legal for home and small business use.
Do I need an engineer to install it?
No. The G1000 is designed for DIY installation in 60–90 minutes with basic tools (drill, screwdriver, spanner, ladder). A step-by-step manual is included, and lifetime technical support is available from Boost4U.
What if I have no outdoor signal?
The G1000 requires at least 1 bar of outdoor 900 MHz signal to work. If you have 0 bars everywhere outside (including at height), no consumer booster can help. Contact your network operator about a mast or femtocell.
Can the G1000 cover a basement and multiple floors?
Yes. The 80 dB gain and 10 dBi panel deliver 2–4 bars to basements and across 4–5 floors. For very deep basements or buildings over 5 storeys, add a second indoor panel via splitter (available separately).
How much does it cost to run?
Approximately £47 per year at £0.27/kWh — less than £4 per month. There are no ongoing fees, subscriptions or contracts.
What is the return policy?
The G1000 comes with a 365-day money-back guarantee. If you are not satisfied for any reason within 365 days of purchase, return the unit for a full refund (minus shipping costs).
Can I use the G1000 in a listed building?
Yes, in most cases. The outdoor antenna can be mounted discreetly at the rear or on an existing chimney without listed building consent. Consult your local conservation officer for guidance. The indoor unit and cable require no consent.
