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.

How the D1000 Works
- Receives: The outdoor Yagi antenna captures weak Band 3 (1800 MHz) signal from the nearest EE/BT mast, mounted on the roof or exterior wall pointing towards the mast.
- Amplifies: The D1000 booster unit amplifies the signal by 60 dB (uplink) and 65 dB (downlink), filtering noise and interference.
- Broadcasts: The indoor panel antenna rebroadcasts the boosted 4G and 2G signal throughout up to 1000 m² of indoor space.
- Returns: Uplink signals from phones and devices are amplified and sent back to the mast via the outdoor antenna.

- 4G data + 2G calls: Boosts both mobile internet and voice calls/SMS simultaneously.
- 1000 m² coverage: Ideal for 5–6 bedroom houses / large office, large flats and small offices.
- 100 simultaneous users: Enough for a family or small office team.
- High gain (65 dB downlink): Powerful amplification for areas with very weak outdoor signal (1–2 bars).
- ≥27 dBm output: Strong broadcast power for reliable coverage throughout the property.
- Expandable: Add extra indoor antennas to cover larger areas or multiple floors.
- 10m outdoor + 5m indoor cable included: Sufficient for most domestic installations from roof to living area.
- Ofcom legal: Licence-exempt, UKCA/CE certified, automatic gain control.
- 365-day returns: Longest money-back guarantee in the market.
Disadvantages
- Band 3 only: Does NOT boost Band 8 (900 MHz) or Band 20 (800 MHz). O2/Vodafone 2G calls on Band 8 are not supported.
- Not for O2/Vodafone: O2 and Vodafone primarily use Band 8 (900 MHz) for 2G and Band 20 (800 MHz) for 4G. The D1000 will not improve their signal.
- Requires outdoor signal: Must have 1–2 bars of Band 3 signal outside. Cannot create signal from nothing.
- 10m antenna separation: Outdoor and indoor antennas must be at least 10m apart vertically to prevent oscillation. This may be challenging in some flats.
- Standard delivery 10–15 days: Not next-day delivery.
- No 5G support: No consumer booster currently supports 5G.
- Professional installation recommended: While DIY is possible, roof mounting and cable routing may require a handyman for some properties.
- Single band only: If your phone uses multiple bands, only Band 3 is boosted. Phones may drop to other bands in weak areas.
- AC power required: Needs a mains power socket near the booster unit.
- Three 4G only: Three customers get 4G data but no 2G calls (Three has no 2G network).

Installation Guide
- Find the signal: Use your phone to find where outdoor Band 3 signal is strongest. Check the mast direction using the CellMapper app or Ofcom coverage checker.
- Mount outdoor antenna: Install the Yagi antenna on the roof, chimney or exterior wall, pointing towards the nearest EE/BT mast. Use the included mast mount or brackets. Ensure it is at least 10m vertically from the indoor antenna.
- Route cable: Run the 10m outdoor cable from the antenna through the wall or loft into the property. Use cable clips to secure. Avoid sharp bends (minimum 25mm radius).
- Connect booster: Plug the outdoor cable into the "BS" port on the booster. Connect the indoor panel antenna to the "MS" port.
- Mount indoor antenna: Place the indoor panel antenna on a wall or ceiling in the central area needing coverage, facing the usage area.
- Power on: Plug the UK power adapter into a mains socket. The booster will calibrate automatically (10–15 seconds).
- Test: Check signal bars on your phone. Run a speed test. Adjust antenna direction if needed.
Installation time: 1–2 hours (DIY). Tools needed: Drill, masonry bits, ladder, cable clips, spanner. Professional installation recommended for roof work.
Frequently Asked Questions
Will the D1000 work in my home?
Yes, if you have EE, BT, ASDA, Virgin, Orange, T-Mobile, TPO, Three, iD, Smarty, Plusnet or Freedom Pop and at least 1–2 bars of outdoor Band 3 (1800 MHz) signal. The D1000 covers up to 1000 m², ideal for 5–6 bedroom houses / large office, large flats and small offices. Check your band before buying.
Does the D1000 improve 4G data speed?
Yes. The D1000 boosts Band 3 (1800 MHz) 4G LTE data, significantly improving download and upload speeds in areas with weak outdoor signal. In our tests, 4G speeds improved from 0.5–2 Mbps to 10–30 Mbps after installation. Actual speed depends on your network's available bandwidth.
Will it work with O2 or Vodafone?
No. The D1000 operates on Band 3 (1800 MHz), which is used by EE/BT/ASDA for 2G and 4G. O2 and Vodafone primarily use Band 8 (900 MHz) for 2G and Band 20 (800 MHz) for 4G. For O2/Vodafone, consider the Boost4U C-series (Band 20) or G-series (Band 8) boosters.
How much area does the D1000 cover?
Up to 1000 m² under ideal conditions (2+ bars outdoor signal, standard construction). Coverage may be reduced in properties with thick stone walls, metal roofing or multiple floors. You can expand coverage by adding extra indoor antennas (sold separately).
Is the D1000 legal to use in the UK?
Yes. The D1000 is Ofcom licence-exempt with UKCA/CE certification. It operates within Ofcom's power limits for 1800 MHz (≥27 dBm) and includes automatic gain control to prevent network interference. No licence is required.
Do I need professional installation?
DIY installation is possible if you're comfortable with roof work and drilling. The kit includes everything needed. However, for roof mounting, we recommend professional installation or a competent handyman. Typical professional installation costs £80–£150.
What if I have 0 bars outside?
The D1000 cannot create signal from nothing. It requires at least 1–2 bars of outdoor Band 3 signal. If you have 0 bars everywhere around your property, no consumer booster will work. Contact your network provider to report a coverage blackspot.
How much does the D1000 cost?
£396.00 GBP including the booster unit, outdoor Yagi antenna, indoor panel antenna, 10m outdoor + 5m indoor cable, UK power adapter and user manual. Free UK shipping. 365-day money-back guarantee included.
What is the return policy?
The D1000 comes with a 365-day money-back guarantee. If it does not improve your signal for any reason within 365 days, return it for a full refund (minus shipping costs). Most signal issues are resolved by repositioning the outdoor antenna.
Can I add more indoor antennas?
Yes. The D1000 supports additional indoor panel antennas (sold separately) to extend coverage to multiple rooms or floors. Each additional antenna covers approximately 100–150 m². A splitter is required for multiple antennas.
