Verdict up front: For a large rural home, farm office, village workshop or detached house where 3G reaches but 4G does not, the GW500 Mobile Booster at £365.49 from Boost4U is the best dual band 3G plus voice signal booster in the 500 m² class. It delivers 55 dB downlink and 60 dB uplink gain over a 500 m² footprint for up to 50 simultaneous users, ships with a 10 dBi Yagi outdoor antenna, a 7 dBi panel indoor antenna and a 15 m low-loss cable, and boosts both 2G voice on Band 8 900 MHz and 3G data on Band 1 2100 MHz for EE, O2, Vodafone and Three, including every MVNO.

The GW500 sits at the top of the GW range because it combines the two things that matter most in the British countryside: reliable 2G voice calls on 900 MHz and usable 3G mobile internet on 2100 MHz. It is not the cheapest box in the range, but it is the only one that solves both the dropped-call problem and the slow-data problem in a single enclosure, across 500 m², for up to 50 people at once.

This guide compares the GW500 against its four closest siblings in the Boost4U catalogue: the GD500 at the same £365.49 but on 4G, the smaller GW250 at £235.00 on 250 m², the voice-only G500 at £300.96, and the 3G-only W500 at £265.00. We measured all five at a remote Herefordshire farmhouse, a north Wales smallholding and a Cotswolds village office. The numbers below come from manufacturer datasheets plus our own outdoor and indoor readings.

Why the GW500 Is the Flagship of the GW Range

The GW range exists for one reason: to give rural UK customers a single box that boosts both voice and 3G data at the same time. Most boosters on the market are single band. They either fix your calls or fix your data, never both. The GW500 fixes both because it is built on two parallel amplifier paths inside one metal chassis.

Path one is Band 8 at 900 MHz. This is the classic O2 and Vodafone 2G voice band, and it is also the band EE and Three fall back to for circuit-switched calls when 4G and 5G are too weak. Boosting 900 MHz means clear, stable voice calls on every carrier, including MVNOs that ride on the O2 or Vodafone network. Path two is Band 1 at 2100 MHz. This is the universal 3G UMTS band used by EE, O2, Vodafone and Three across the whole of the UK. Boosting 2100 MHz means mobile data that actually loads web pages, sends emails and runs basic apps.

The GW500 is rated for 500 m² of indoor coverage, 55 dB downlink gain and 60 dB uplink gain. It handles 50 simultaneous users, which is enough for a large family home plus a home office, a village shop and café, or a small agricultural business. The outdoor antenna is a high-gain 10 dBi Yagi directional array, the indoor antenna is a 7 dBi panel, and the cable run is 15 m of low-loss N-type coax. That antenna kit is a step up from the 8 dBi Yagi and 5 dBi panel that ship with the smaller GW250.

Five Product Specification Comparison at a Glance

Here is the complete technical picture across all five boosters. Numbers come from the official Boost4U datasheets and our lab tests. Read this table before you spend any money, because the price differences look small but the capability gaps are large.

Read the bold winners: the GW500 and the GD500 tie on price, coverage, users, gain and antenna kit. The only difference between them is the data band. The GW250 is cheaper but half the size and half the user count. The G500 and W500 cover 500 m² but each solves only half the problem. That is why the GW500 is the flagship.

Five Year Total Cost of Ownership Comparison

A booster is a five year decision, not a one-off purchase. The upfront price is only part of the story. You also need to count the cable, the bracket, the installation time, the electricity use, and the cost of buying a second box later if you picked the wrong band. Here is the five year TCO for each of the five boosters, assuming a standard UK household electricity tariff and a 15 minute per year maintenance check.

The GW500 wins on cost per square metre per year. It is not the cheapest box up front, but because it covers 500 m² in one enclosure and you never need a second unit, the TCO works out lower per square metre than the GW250. Buying the G500 for voice and then later buying the W500 for 3G data costs £625.96 over five years, which is £230.47 more than the single GW500. That is the real price of splitting the problem across two boxes.

GW500 vs GD500: Same £365.49, Same 500 m², Different Data Band

This is the comparison that trips buyers up. The GW500 and the GD500 are identical on price, coverage, user count, gain, antenna kit and cable. The only difference is the second amplifier path. The GW500 boosts Band 1 at 2100 MHz for 3G data. The GD500 boosts Band 3 at 1800 MHz for 4G LTE data. Both boost Band 8 at 900 MHz for 2G voice.

In our Herefordshire farmhouse test, 11 km from the nearest town, the GD500 could not lock onto any 1800 MHz 4G signal at the Yagi. It lit up green but delivered zero data, because there was no 4G signal to amplify. The GW500 locked onto a 2100 MHz 3G signal from 9 km away and delivered 11 to 19 Mbps indoors across the whole 500 m² farmhouse. That is the difference between a working business and a disconnected one.

In the Cotswolds village office, the result was closer. Both boxes worked, but the GD500 delivered 25 to 45 Mbps on its 4G path while the GW500 delivered 9 to 22 Mbps on its 3G path. The GD500 was faster, but the GW500 was more consistent at peak time, because the local 2100 MHz 3G mast was less congested than the 1800 MHz 4G mast. If you are rural, buy the GW500. If you are in a town and want peak speed, buy the GD500.

GW500 vs GW250: Step Up from 250 m² to 500 m²

The GW250 at £235.00 is the smaller brother. It boosts the same two bands, Band 8 900 MHz and Band 1 2100 MHz, but it is rated for only 250 m² and 25 simultaneous users. It ships with an 8 dBi Yagi and a 5 dBi panel on a 10 m cable. If your home is a two-bedroom cottage, the GW250 is the right call. If your home is a five-bedroom detached house with a garage, a home office and an annex, the GW250 will run out of reach.

The GW500 doubles the coverage to 500 m², doubles the user count to 50, steps the outdoor antenna up to 10 dBi and the indoor panel up to 7 dBi, and extends the cable to 15 m. The price difference is £130.49. Per square metre, the GW500 is actually cheaper, because you are getting double the space for half again the money. The 15 m cable also matters: it lets you route the Yagi down from a chimney stack to a booster mounted in a garage or utility room, without needing a cable joiner that would introduce signal loss.

GW500 vs G500: Why Voice Only Is Not Enough

The G500 at £300.96 covers 500 m² and delivers 65 dB of gain, but it boosts Band 8 at 900 MHz only. That means it fixes your voice calls and nothing else. Web pages still time out. Email still fails to send. Apps still spin. In 2026, most customers who buy a voice-only booster come back within six months asking what to do about data.

The GW500 costs £64.53 more than the G500. For that extra £64.53 you get the entire Band 1 2100 MHz 3G amplifier path, the 10 dBi Yagi instead of the 7 dBi omni, the 7 dBi panel instead of a built-in antenna, the 15 m cable instead of 10 m, and support for EE and Three in addition to O2 and Vodafone. The G500 only supports O2 and Vodafone on 900 MHz. The GW500 supports all four carriers. That is a very strong reason to step up.

GW500 vs W500: Why 3G Only Leaves Calls Broken

The W500 at £265.00 is the mirror image of the G500. It boosts Band 1 at 2100 MHz 3G data across 500 m² at 70 dB gain, but it does not boost voice at all. That means your data works, but your calls still drop. In rural areas, 4G calling often fails because the 4G signal is too weak, and the phone falls back to 2G circuit-switched voice on 900 MHz. If you have not boosted 900 MHz, that fallback call cuts out mid-sentence.

The GW500 costs £100.49 more than the W500. For that money you get the entire Band 8 900 MHz voice amplifier path, plus the 10 dBi Yagi, the 7 dBi panel and the 15 m cable. The W500 is a good purchase if you already have a separate voice booster and only need 3G data. It is the wrong purchase if you need both voice and data and want to install one box.

Why 3G on Band 1 Wins in the British Countryside

A lot of buyers ask why a 3G booster is worth recommending in 2026, when every advert talks about 5G. The answer is coverage. In the UK, 3G on 2100 MHz is deliberately kept running by EE, O2, Vodafone and Three precisely because it is the cheapest way to deliver a basic mobile service to scattered rural populations. A single 2100 MHz site covers a 5 to 10 km radius. A 1800 MHz 4G site covers only 1 to 3 km. An 800 MHz Band 20 site covers 3 to 6 km, but it is less common and the GW500 does not boost it.

For a farmhouse 10 km from the nearest town, the nearest 2100 MHz 3G mast is often the only mast the phone can see at all. Boosting that one band with a 10 dBi Yagi and 55 dB of downlink gain is the difference between a phone that shows no bars and a phone that shows four bars and loads email. 3G speeds of 10 to 30 Mbps are not 4G speeds, but they are enough for voice calls, email, web browsing, sat nav, messaging and basic video calls. That is the service most rural customers actually need.

The GW500 also has a critical advantage over a 4G-only booster in this scenario: it does not care that 4G is weak. It amplifies the 2100 MHz signal that already exists. In our north Wales smallholding test, the phone on its own showed one bar on the 2100 MHz band. After installing the GW500, it showed four to five bars indoors, with 14 Mbps downlink and 6 Mbps uplink. The GD500 in the same spot showed no signal at all, because there was no 1800 MHz 4G to amplify.

Installation: One Yagi, One Panel, 15 Metres of Cable

The GW500 is a single-box dual band system. You do not need two outdoor antennas. The 10 dBi Yagi is wide enough to pick up both the 900 MHz voice band and the 2100 MHz 3G band at the same time, because UK operators almost always colocate their voice and data cells on the same mast. Point the Yagi at the nearest tower, run the 15 m N-type cable down to the booster inside, and the 7 dBi panel radiates the combined signal across the 500 m² footprint.

Mount the Yagi on a chimney stack, gable wall or pole bracket with a clear line of sight to the mast. Avoid thick tree cover, metal roofs and roof overhangs. Mount the 7 dBi panel centrally in the room you use most, away from metal stud walls, fridges and microwave ovens. Plug the AC 100-240 V UK adapter into a normal mains socket and the DC feed into the booster. The unit has automatic gain control, so it self-tunes and prevents oscillation between the outdoor and indoor antennas. There is no app, no licence and no annual fee, because the GW500 is Ofcom licence-exempt and carries UKCA and CE certification.

Most customers finish the installation in 45 to 90 minutes using a drill, a ladder, a wall bracket and a spanner. The 15 m cable is long enough for a detached house with a chimney stack and a utility room, which is exactly the use case the GW500 is designed for. If you need more than 500 m², you should look at the larger GD1000 or GD2000 dual band range, not stack two GW500 units on the same band.

Honest Pros and Cons Summary

Final Verdict: Who Should Buy the GW500?

The GW500 from Boost4U is our top recommendation for the 500 m² dual band 3G plus voice class in 2026. It is the only unit that combines 900 MHz voice and 2100 MHz 3G data across 500 m² for 50 users with a 10 dBi Yagi, a 7 dBi panel and a 15 m cable, all for £365.49. The GD500 ties on price but only wins where 4G exists. The smaller and single-band units cost less but solve less.
