GDW250 vs GD250 vs GW250 UK 2026: £435 Tri-Band 2G+4G+3G vs £235 Dual-Band 4G vs £235 Dual-Band 3G 250m² Booster
Stuck between the £435.00 GDW250 tri-band and the £235.00 GD250 or GW250 dual-band? We dissect the £200 gap, the band trade-offs, and exactly who should buy which.
Verdict up front: if you need 2G voice calls, 4G LTE data and 3G fallback across more than one UK carrier inside a 250 m² space, the GDW250 at £435.00 is the only one-box answer. If you need only voice plus 4G, the GD250 at £235.00 saves you £200. If you need only voice plus 3G, the GW250 at £235.00 saves you £200. The £200 premium on the GDW250 buys you the third band, a bigger Yagi, a bigger indoor panel, a longer cable and five extra simultaneous users.
This is not a generic comparison. All three units are made by the same Boost4U engineering line, all three carry UKCA and CE certification, all three are Ofcom licence-exempt, and all three are rated for 250 m². The differences are deliberate and narrow: which two or three frequencies the RF chain is tuned to, and how much antenna gain and cable length you get. If you understand those differences, you will not overspend on the GDW250 when a GD250 would do, and you will not underspend on a GD250 when your household actually needs Band 1.
The GDW250 is the first tri-band combination repeater in this product family. It adds Band 1 at 2100 MHz to the existing Band 8 at 900 MHz and Band 3 at 1800 MHz recipe. The GD250 is the Band 8 plus Band 3 machine, optimised for voice plus 4G. The GW250 is the Band 8 plus Band 1 machine, optimised for voice plus 3G. Every other component, from the UK 3-pin power supply to the automatic gain control chip, is shared across the three units. The £200 gap is entirely the cost of the third RF chain and the upgraded antennas.
The Core Difference: Three Bands vs Two Bands
The simplest way to understand the three products is to draw a table of which service layers each one touches. Band 8 at 900 MHz carries 2G voice for O2, Vodafone and EE. Band 3 at 1800 MHz carries 4G LTE data for EE and Three. Band 1 at 2100 MHz carries 3G UMTS data for all four operators.
The GD250 touches Band 8 and Band 3. That means it fixes dropped calls on O2, Vodafone and EE, and it fixes slow 4G data on EE and Three. But if a Three user in a rural area falls back to 3G because 4G is not available, the GD250 does nothing for them. The GW250 touches Band 8 and Band 1. That means it fixes dropped calls on O2, Vodafone and EE, and it fixes 3G data for all four operators. But if an EE user in a town expects 4G LTE speeds, the GW250 leaves them on 3G.
The GDW250 touches all three. It fixes the dropped calls, it fixes the 4G data, and it fixes the 3G fallback, all through the same Yagi antenna and the same box. That is the entire pitch. The question is whether your household actually needs all three layers, or whether one of the dual-band units is enough.
There is a second, subtler difference. Because the GDW250 carries three bands, it needs a more directional outdoor antenna to isolate them from each other and from neighbouring cells. That is why it ships with a 10 dBi Yagi instead of the 8 dBi Yagi on the GD250 and GW250. The extra 2 dBi of antenna gain more than compensates for the slightly lower per-band amplifier gain, which stays at 50 to 55 dB on all three units. The indoor panel also steps up from 5 dBi to 7 dBi, and the cable from 10 m to 15 m.
Head-to-Head Specification Table: GDW250 vs GD250 vs GW250
The table below compares the three units across every parameter that changes between them. Shared parameters, like UKCA certification, Ofcom licence-exempt status and 250 m² rated coverage, are listed once and noted as identical.
| Parameter | GDW250 £435.00 | GD250 £235.00 | GW250 £235.00 |
|---|---|---|---|
| Architecture | Tri-band combo | Dual band 4G | Dual band 3G |
| Band 8 900 MHz 2G voice | Yes | Yes | Yes |
| Band 3 1800 MHz 4G LTE | Yes | Yes | No |
| Band 1 2100 MHz 3G UMTS | Yes | No | Yes |
| Voice calls (all 4 networks) | Yes, Band 8 | Yes, Band 8 | Yes, Band 8 |
| 4G LTE data | EE + Three on Band 3 | EE + Three on Band 3 | Not boosted |
| 3G data | All 4 networks on Band 1 | Not boosted | All 4 networks on Band 1 |
| Max uplink gain | 50 dB | 50 dB | 50 dB |
| Max downlink gain | 55 dB | 55 dB | 55 dB |
| Coverage area | 250 m² | 250 m² | 250 m² |
| Simultaneous users | 30 | 25 | 25 |
| Outdoor antenna | 10 dBi Yagi | 8 dBi Yagi | 8 dBi Yagi |
| Indoor antenna | 7 dBi panel | 5 dBi panel | 5 dBi panel |
| Coaxial cable | 15 m low-loss | 10 m low-loss | 10 m low-loss |
| Networks covered | EE, O2, Vodafone, Three | EE, O2, Vodafone, Three | EE, O2, Vodafone, Three |
| UKCA / CE / Ofcom exempt | Yes | Yes | Yes |
| Price | £435.00 | £235.00 | £235.00 |
| Price gap to GDW250 | Baseline | £200 cheaper | £200 cheaper |
Notice that the gain numbers are identical across all three units at 50 uplink and 55 downlink. This is not a coincidence. The Boost4U amplifier module is the same; the difference is how many frequency channels it splits across. The GDW250 compensates for splitting power three ways by using a 10 dBi Yagi instead of an 8 dBi Yagi. In field testing, the three units deliver the same 250 m² coverage on the bands they each support.
The £200 Price Gap: What You Actually Gain by Upgrading
The GDW250 costs £435.00. The GD250 and GW250 each cost £235.00. That is a £200 gap. Before you decide whether it is worth it, let us break down exactly what that £200 buys.
| Upgrade item | GDW250 £435 | GD250 / GW250 £235 | Value of upgrade |
|---|---|---|---|
| Third RF chain (Band 1 or Band 3) | Present | Absent | Covers the missing service layer |
| Outdoor Yagi gain | 10 dBi | 8 dBi | +2 dBi pulls weaker towers |
| Indoor panel gain | 7 dBi | 5 dBi | +2 dBi evens room-to-room |
| Cable length | 15 m | 10 m | +5 m reaches further eaves |
| Simultaneous users | 30 | 25 | +5 users for small offices |
| Second booster avoided | No need | Yes, +£235 | Saves £235 vs buying both |
| Realistic 5-year cost | £452.76 | £484.80 (with second booster) | GDW250 saves £32 over 5 years |
The key insight is that if you ever need both the missing band from a GD250 and the missing band from a GW250, you would have to buy both units. That costs £470 upfront, requires two Yagi antennas, two cable runs and two power supplies. The GDW250 at £435 does the same job in one box, saves £35 on hardware, and uses half the wall space. The £200 premium only makes sense if you actually need the third band. If you do not, the GD250 or GW250 is the rational buy.
Honest Pros and Cons: All Three Side by Side
| Unit | Pros | Cons |
|---|---|---|
| GDW250 £435 | Pro 1: Only one-box tri-band covering 2G voice, 4G LTE and 3G data across all four UK networks. Pro 2: 10 dBi Yagi and 7 dBi indoor panel deliver stronger signal than the dual-band units. Pro 3: 30 simultaneous users suit family plus home office plus small retail. Pro 4: 15 m cable reaches further from eaves to hallway. Pro 5: Avoids buying two separate boosters for mixed-layer households. |
Con 1: £435.00 is £200 more than either dual-band unit if you only need two layers. Con 2: Tri-band Yagi requires more precise mast alignment than the dual-band units. Con 3: No 5G, no Band 20 800 MHz, no Band 7 2600 MHz. Con 4: Longer install at 45 to 90 minutes versus 30 to 60 minutes. Con 5: LED-only status, no smartphone app. |
| GD250 £235 | Pro 1: Cheapest way to get 2G voice plus 4G LTE across all four networks in one box. Pro 2: Ideal for town and city homes where 4G is the default data layer. Pro 3: 8 dBi Yagi and 5 dBi panel deliver reliable 250 m² coverage. Pro 4: 25 simultaneous users suit a typical family. Pro 5: £200 cheaper than the GDW250 if 3G fallback is not needed. |
Con 1: No Band 1 2100 MHz, so rural Three and O2 3G fallback stays weak. Con 2: 8 dBi Yagi and 5 dBi panel are 2 dBi below the GDW250 on each antenna. Con 3: 10 m cable is 5 m shorter than the GDW250. Con 4: 25 users versus the GDW250's 30. Con 5: Would need a GW250 at £235 to add 3G later. |
| GW250 £235 | Pro 1: Cheapest way to get 2G voice plus 3G data across all four networks in one box. Pro 2: Ideal for rural villages where 3G is the only available data layer. Pro 3: 8 dBi Yagi and 5 dBi panel deliver reliable 250 m² coverage. Pro 4: 25 simultaneous users suit a typical family. Pro 5: £200 cheaper than the GDW250 if 4G LTE is not available at your mast. |
Con 1: No Band 3 1800 MHz, so EE and Three 4G LTE stays slow or absent. Con 2: 8 dBi Yagi and 5 dBi panel are 2 dBi below the GDW250 on each antenna. Con 3: 10 m cable is 5 m shorter than the GDW250. Con 4: 25 users versus the GDW250's 30. Con 5: Would need a GD250 at £235 to add 4G later. |
Scenario Decision Tree: Which One Should You Actually Buy?
The fastest way to decide is to answer three questions about your household. Work down the tree and stop at the first branch that describes you.
Question 1: Do you have at least one family member on Three or O2 who relies on 3G data in a rural or semi-rural area, AND at least one person on EE or Three who needs 4G LTE indoors? If yes, buy the GDW250 at £435.00. You need both Band 3 and Band 1, and buying a GD250 plus a GW250 would cost £470 and require two antennas. The GDW250 is cheaper and simpler.
Question 2: Does everyone in your household get usable 3G outdoors, but EE or Three 4G is painfully slow indoors, and dropped O2/Vodafone/EE calls are the other complaint? If yes, buy the GD250 at £235.00. You need Band 8 for voice and Band 3 for 4G. You do not need Band 1 because 3G works outdoors already. The GD250 saves you £200.
Question 3: Do you live in a village or rural hamlet where 4G has not yet arrived, and your only data option is 3G on Band 1, plus dropped calls on Band 8? If yes, buy the GW250 at £235.00. You need Band 8 for voice and Band 1 for 3G. Band 3 at 1800 MHz is not available at your mast, so paying for the GDW250's Band 3 circuitry would be wasted. The GW250 saves you £200.
Question 4: Are you a small business, village shop, holiday let or mixed-use property where the SIM mix is unpredictable and guests come and go? If yes, buy the GDW250 at £435.00. You cannot choose which networks your customers or guests bring. The tri-band box covers every combination. The 30-user rating also matters in a retail or holiday-let setting.
Gain Trade-off Explained: Why All Three Say 50/55 dB
Looking at the spec sheet, all three units list 50 dB uplink and 55 dB downlink. A common question is whether the GDW250 splits its amplifier power three ways, making each band weaker. The answer is no, but the reasoning is subtle.
The Boost4U amplifier module is rated for a total conducted output power. When that power is split across two bands on the GD250 or GW250, each band gets roughly half the total. When it is split across three bands on the GDW250, each band gets roughly one third on paper. In practice, the GDW250 compensates two ways: first, the 10 dBi Yagi outdoor antenna pulls in a stronger incoming signal from the mast, which means the amplifier has more to work with; second, the 7 dBi indoor panel radiates the amplified signal more efficiently into the rooms. The net result is that all three units deliver the same 250 m² coverage on the bands they support.
The trade-off shows up in very weak-signal situations. If your outdoor signal on Band 3 is only one bar, the GD250 with its 8 dBi Yagi might deliver 2 bars indoors, while the GDW250 with its 10 dBi Yagi might deliver 3 bars. The extra antenna gain is the difference. If your outdoor signal is already 3 or 4 bars, all three units deliver solid indoor coverage and you will not notice the antenna difference.
Final Verdict: Buy the GDW250 If, Buy the GD250 If, Buy the GW250 If
Buy the GDW250 at £435.00 if: your home or small office mixes people on EE, O2, Vodafone and Three; if some users need 4G LTE on EE or Three while others need 3G fallback on Three or O2; if you run a small shop, holiday let or home office where guest SIMs are unpredictable; or if you would otherwise need to buy both a GD250 and a GW250. The tri-band box is cheaper than the sum of the two dual-band boxes.
Buy the GD250 at £235.00 if: everyone in your household gets usable 3G outdoors, your pain is dropped O2/Vodafone/EE calls plus slow EE/Three 4G indoors, and you live in a town or city where Band 3 at 1800 MHz is the primary 4G layer. You do not need Band 1, and the £200 saving is better spent elsewhere.
Buy the GW250 at £235.00 if: you live in a rural village where 4G has not arrived, your only data layer is 3G on Band 1, and your other pain is dropped calls on Band 8. Paying for the GDW250's Band 3 circuitry would be wasted because no nearby mast broadcasts 4G at 1800 MHz. The GW250 saves you £200.
Do not buy two dual-band boosters thinking it is cheaper. A GD250 at £235 plus a GW250 at £235 costs £470, requires two Yagi antennas on your roof, two 10 m cable runs, two power supplies and two wall sockets. The GDW250 at £435 does the same job in one enclosure with one antenna. The only reason to buy two is if the two kits serve different buildings more than 30 m apart.
The Bottom Line
The GDW250 at £435.00 is the right choice when your 250 m² home or small office needs 2G voice, 4G LTE and 3G data across more than one UK network. The GD250 at £235.00 is the right choice when you need voice plus 4G but 3G is already fine outdoors. The GW250 at £235.00 is the right choice when you need voice plus 3G but 4G has not reached your mast. The £200 gap buys the third band, a 10 dBi Yagi, a 7 dBi panel, a 15 m cable and 30 simultaneous users. Spend it only if you actually need what it buys.
Frequently Asked Questions
Which should you buy, the GD250 or the GW250, if your budget cannot stretch to the GDW250?
It depends on which data layer you actually need. If you live in a town or city and your pain is slow EE or Three 4G indoors, buy the GD250 at £235.00. If you live in a village where 4G has not arrived and 3G is your only data option, buy the GW250 at £235.00. Both units cover Band 8 voice identically. The only difference is whether they amplify Band 3 for 4G or Band 1 for 3G.
What happens if I buy the GD250 but later need 3G data?
You would need to add a GW250 at £235.00 as a second unit, which means a second Yagi antenna, a second cable run and a second power supply. The combined cost of £470 exceeds the GDW250 at £435.00. If you suspect your area will stay 3G-dependent for several years and you also need 4G, the GDW250 is the safer long-term buy.
Does the £200 GDW250 premium make long-term financial sense?
Over five years, the GDW250 costs £452.76 including electricity. A GD250 plus a GW250 costs £484.80 including electricity. The GDW250 saves about £32 over five years, halves the installation work, uses one antenna instead of two, and supports 30 users instead of two units sharing 25 plus 25. The £200 premium is recovered within the first five years if you genuinely need both missing bands.
Which direction should the GDW250 Yagi point for all three bands?
The 10 dBi Yagi on the GDW250 should point toward the mast that serves the weakest of your three bands. In most UK locations, EE and Three share masts, and O2 and Vodafone share masts. Use the Ofcom sitefinder to locate the nearest mast on each band, then point the Yagi at the mast that serves the band you are weakest on. The other two bands are usually received well enough on the same bearing.
Can I use two dual-band boosters instead of one GDW250?
Yes, but it costs more and installs more work. A GD250 at £235 plus a GW250 at £235 totals £470, which is £35 more than the GDW250. You also need two outdoor antennas, two indoor antennas, two cable runs and two power supplies. The only scenario where two dual-band units beat one GDW250 is when the two coverage areas are more than 30 m apart, such as a house and a separate outbuilding.
How does the 10 dBi Yagi on the GDW250 compare to the 8 dBi on the GD250 and GW250?
10 dBi is 2 dB higher gain than 8 dBi. In real terms, that means the GDW250 Yagi pulls in roughly 60 percent more signal power from the same distant mast. This matters most when your outdoor signal is one to two bars. If your outdoor signal is three bars or more, you will not notice the difference. The extra 2 dB also helps isolate the three bands from each other, which prevents oscillation in tri-band operation.
What if my home only has EE 4G and O2 voice - do I need the GDW250?
No. If your household is purely EE for 4G and O2 for voice, the GD250 at £235.00 is enough. Band 8 on the GD250 carries O2 voice, and Band 3 on the GD250 carries EE 4G. You do not need Band 1 at 2100 MHz unless someone in the house is on Three or relies on 3G fallback. The GDW250's third band would be unused.
Is the 30-user rating on the GDW250 worth it for a family of four?
Not by itself. A family of four uses at most four concurrent connections, well within the GD250's 25-user rating. The 30-user figure matters only if you run a home office with several staff, a village shop with customers using Wi-Fi calling, or a holiday let with multiple guests. If you are purely residential, choose based on the band coverage, not the user count.
What installation differences should I expect between the three units?
The GD250 and GW250 take 30 to 60 minutes to install. The GDW250 takes 45 to 90 minutes because the 10 dBi Yagi needs more precise alignment across three bands, the 7 dBi indoor panel needs careful placement on the middle floor, and the 15 m cable run needs more planning. All three units include an N-type connector, a UK 3-pin power supply and a wall bracket. No drilling of masonry is required beyond a small cable entry hole.
Will the GDW250 become obsolete when 2G is switched off in the UK?
Ofcom has announced a phased 2G switch-off starting after 2033, with no confirmed nationwide shutdown date. Until then, Band 8 at 900 MHz remains the primary voice layer for O2 and Vodafone. When 2G does switch off, voice will move to 4G LTE calling (VoLTE) on Band 3, which the GDW250 already boosts. The GDW250 is therefore future-proof for voice even after 2G shutdown, because its Band 3 circuitry carries both 4G data and future VoLTE calls.
