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 GD500 Works
- Receives: The outdoor 8 dBi Yagi antenna captures weak EE/O2/Vodafone/Three Dual Band 8 & 3 (900 & 1800 MHz) signal from the nearest mast.
- Amplifies: The booster unit amplifies the signal by up to 55 dB (downlink) while filtering noise and interference.
- Broadcasts: The indoor antenna rebroadcasts the boosted signal throughout up to 500 m², supporting 50 simultaneous users.
- Returns: Uplink signals from your phone are amplified and sent back to the mast via the outdoor antenna.
Pros & Cons
Advantages
- Dual 2G + 4G: Boosts both voice calls/SMS and 4G LTE data on Band 3 — unlike call-only boosters.
- EE-optimised: Specifically designed for EE, O2, Vodafone and Three, the UK's largest network group.
- 500 m² coverage: Suitable for 3–5 bedroom houses, small offices, shops and pubs.
- 50 simultaneous users: Supports households and small businesses with multiple devices.
- Complete kit: Everything included — antennas, cables (10m outdoor + 5m indoor), power adapter, brackets. No extra purchases needed.
- Affordable: At £365.49, one of the cheapest dual 2G+4G boosters for EE in the UK.
- Ofcom legal: Licence-exempt, UKCA/CE certified, automatic gain control prevents network interference.
- 365-day returns: Longest money-back guarantee in the UK market — risk-free trial.
- Free UK shipping: No additional delivery costs.
- DIY installation: 30–60 minutes with basic tools, no engineer required.
Disadvantages
- Band 3 only (1800 MHz): Does not boost Band 8 (900 MHz) or Band 20 (800 MHz) signals. Check your phone's band before buying.
- Not for O2/Vodafone: Optimised for EE/O2/Vodafone/Three. O2 and Vodafone customers should choose the C-series (Band 20) or G-series (Band 8).
- 500 m² limit: Not suitable for properties larger than 500 m² — consider the C500 or C1000 for larger spaces.
- Requires 1–2 bars outdoor signal: Cannot create signal from nothing. If you have 0 bars outside, no booster will work.
- 10 m cable included: May need a 20 m upgrade for two-storey houses with roof mounting (available at checkout).
- 10 m antenna separation: Requires adequate vertical distance between outdoor and indoor antennas to prevent oscillation.
- Standard delivery 10–15 days: Not next-day delivery. Plan ahead if needed urgently.
- No 5G support: No consumer booster currently supports 5G. The GD500 handles 2G and 4G only.
- Directional outdoor antenna: Must be pointed toward the nearest EE mast for optimal performance.
- Indoor antenna is 5 dBi: Lower gain than premium models — suitable for 500 m² but not larger.

- Mount outdoor antenna: Install the 8 dBi Yagi on an exterior wall, pole or chimney at 3–5 m height, pointed toward the nearest EE mast.
- Run cable: Route the 10 m coaxial cable from the outdoor antenna to the booster location inside. Upgrade to 20 m at checkout if needed.
- Connect booster: Connect outdoor cable to the BS port, indoor antenna to the MS port, plug in power.
- Maintain separation: Ensure at least 10 m vertical distance between outdoor and indoor antennas to prevent oscillation.
- Test and adjust: Power on, check LED indicators, test signal bars throughout the property. Adjust the outdoor antenna direction for best results.
Installation time: 30–60 minutes. Tools needed: Drill, screwdriver, spanner, ladder.
Frequently Asked Questions
Will the GD500 work with my network?
Yes. The GD500 boosts Dual Band 8 & 3 (900 & 1800 MHz), which all four UK networks use for 2G calls and 4G data. It supports EE, O2, Vodafone, Three and all their MVNOs. To confirm, dial *3001#12345#* on iPhone → Serving Cell Info → check Freq Band Indicator, or use LTE Discovery on Android.
Does the GD500 improve 4G data speed?
Yes. The GD500 amplifies 4G LTE signals on Dual Band 8 & 3 (900 & 1800 MHz), which can improve data speeds from 1–5 Mbps (no signal) to 10–30 Mbps (good signal), depending on your nearest mast's capacity and backhaul.
Will it work with O2 or Vodafone?
No. The GD500 is a Dual Band 8 & 3 (900 & 1800 MHz) booster optimised for EE, O2, Vodafone and Three. O2 and Vodafone primarily use Band 8 (900 MHz) for calls and Band 20 (800 MHz) for 4G. For O2/Vodafone, choose the Boost4U C250 (Band 20 4G) or G250 (Band 8 calls).
What size property does the GD500 cover?
Up to 500 m², which is typically a 3–5 bedroom house, a small office, a shop or a pub. Actual coverage depends on outdoor signal strength, building materials and antenna placement. For properties over 500 m², consider the C500 (500 m²) or C1000 (1000 m²).
Is the GD500 legal in the UK?
Yes. The GD500 is Ofcom licence-exempt with UKCA/CE certification. It operates within Ofcom's power limits and includes automatic gain control (AGC) to prevent interference to the mobile network. Legal for home and business use without a licence.
How much does the GD500 cost?
£365.49 GBP including the booster, outdoor antenna, indoor antenna, 10 m cable, UK power adapter, mounting brackets and user manual. Free UK shipping. Optional upgrades: 20 m cable, high-gain antenna, surge protector.
What if there is no signal outside my house?
The GD500 can only amplify existing signal — it cannot create signal from nothing. You need at least 1–2 bars of outdoor EE Band 3 signal. If you have 0 bars everywhere outside, contact EE to report a coverage issue — no consumer booster can help in that situation.
How many phones can use the GD500 at once?
Up to 50 simultaneous users. This is sufficient for most households and small businesses. The booster amplifies the signal for all devices in range, not a fixed number — all 25 can be on calls or data simultaneously.
What is the return policy?
The GD500 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). This is the longest return policy in the UK signal booster market.
How long does delivery take?
Standard UK delivery is 10–15 business days with free shipping. Express delivery may be available at checkout for an additional fee. The GD500 is shipped from the UK warehouse.
