In areas with no 900/2100 MHz 4G, coverage is limited. - **100 m² max coverage:** Covers a car cabin or small caravan; large motorhomes may need an extended antenna kit. - **Requires at least 1 bar outdoors:** A booster cannot create signal where none exists — the magnetic antenna must receive a usable signal. - **Standard cable is 5 m:** Larger vehicles or caravans may need a cable extension. - **No built-in LCD / signal meter:** Uses LED indicators only — fine for most users but less precise for optimisation. - **Standard delivery 10–15 days:** Not next-day; express delivery available at extra cost. - **5V DC only (included):** For 240 V mains use in a static caravan, an optional AC adapter is needed. ## How the CVGW Works The CVGW is a bidirectional RF repeater designed for mobile environments. Three-step signal path: 1. **Capture:** The magnetic-mount outdoor antenna on the vehicle roof picks up the weak 900/2100 MHz 3G signal from the nearest mast. 2. **Amplify:** The booster unit filters and amplifies both downlink (tower-to-phone) and uplink (phone-to-tower) signals by 45/40 dB. 3. **Redistribute:** The indoor whip antenna rebroadcasts the amplified signal inside the vehicle cabin or caravan, and relays phone signals back to the mast. ## Installation Steps (Under 15 Minutes) 1. Find the strongest signal spot on the vehicle roof (usually the centre or front) using your phone's signal bars. 2. Place the magnetic-mount outdoor antenna on the roof at that spot. The magnet holds it securely at motorway speeds. 3. Run the 5 m cable from the roof antenna through the door seal or window into the vehicle. 4. Place the booster unit under a seat or in the glove compartment. Screw on the indoor whip antenna. 5. Plug the 5V DC adapter into the cigarette-lighter socket. The LED indicators will show power and signal status. 6. Wait 30–60 seconds for sync, then test signal bars on your phone inside the vehicle. ## Frequently Asked Questions (10 Real UK User Questions) ### 1\. Does the CVGW work with 5G? No. The CVGW is a 3G Dual Band 8 & 1 (900 & 2100 MHz) booster only. It does not amplify 5G frequencies. However, 3G remains the primary voice and data layer for most UK users on the move, and VoLTE calls work perfectly. For 5G boosting in vehicles, consider a multi-band 5G vehicle booster. ### 2\. Will this booster work in my car on EE, O2, Vodafone or Three? Yes. EE and Vodafone use Dual Band 8 & 1 (900 & 2100 MHz) for 3G coverage on UK roads. The CVGW is compatible with EE, O2, Vodafone, Three and all their MVNOs (BT, ASDA, Virgin, Orange, T-Mobile, Plusnet, TPO). O2 and Three use different bands (Band 3/20) and are not supported. ### 3\. Can I use the CVGW in a caravan or motorhome? Yes. The CVGW is designed for cars, vans, motorhomes and static caravans. The magnetic antenna mounts on the roof of a motorhome or caravan, and the 5V DC adapter plugs into the vehicle's cigarette lighter. For static caravans with 240 V mains, an optional AC power adapter is available. The 100 m² coverage suits most caravan interiors. ### 4\. Is a car mobile signal booster legal in the UK? Yes, provided the device meets Ofcom's licence-exempt mobile repeater specifications. The CVGW is UKCA / CE certified and operates within Ofcom's Technical Standard for Mobile Repeaters, which permit licence-exempt use of repeaters that meet strict power and filtering limits. Uncertified, high-power boosters remain illegal. ### 5\. Do I need an outdoor signal for the booster to work while driving? Yes. A booster amplifies an existing signal — it cannot create one. You need at least 1 bar of usable 3G (Dual Band 8 & 1) signal at the roof antenna. The CVGW works well while driving through rural areas with intermittent signal, as it continuously amplifies whatever signal the roof antenna receives. In complete blackspots with zero bars, no booster can help. ### 6\. Will the magnetic antenna stay on at motorway speeds? Yes. The magnetic-mount antenna is designed for vehicle use at UK motorway speeds (up to 70 mph / 113 km/h). The strong neodymium magnet holds firmly to steel roofs. For aluminium or fibreglass roofs (common on some caravans and motorhomes), use the included adhesive mounting pad or the optional permanent screw-mount bracket. ### 7\. Can multiple passengers use the boosted signal at the same time? Yes. The CVGW supports 15 simultaneous users and devices. There is no per-device cap — the driver and all passengers can make calls, stream music and browse simultaneously. Performance depends on the available mast bandwidth, not the booster itself. ### 8\. How is the CVGW different from a home booster like the C100? The CVGW uses a 5V DC car power adapter and a magnetic-mount roof antenna designed for vehicles, while the C100 uses a 240 V mains adapter and a wall-mounted outdoor antenna for fixed buildings. Both boost the same Dual Band 8 & 1 2G+3G frequency with 45/40 dB gain. The CVGW is for cars, vans and caravans; the C100 is for homes and offices. ### 9\. What is the return policy and warranty? The CVGW comes with a 365-day money-back guarantee — if you are not satisfied, return it within 365 days for a full refund. Boost4U also provides lifetime technical support via email and live chat. The hardware is covered by a standard manufacturer warranty against defects. ### 10\. How long does UK delivery take and is shipping free? Standard UK shipping is free and takes 10–15 business days. Orders are dispatched within 1–2 business days. Express / expedited delivery is available at checkout for an additional fee. EU and European orders (DE, FR, IT, ES, NL, BE, AT, SE, DK, FI, IE, PT, PL, CZ) are also accepted with 1–2 business day dispatch. ## Related Guides & Reviews - [Best Car Mobile Signal Booster UK 2025: Top 5 Compared (CVGW Ranked #1)](https://www.ukmobilebooster.com/en-gb/blogs/news/cvgw-best-car-mobile-signal-booster-uk-2025-top-5-compared-tested) - [Boost4U CVGW Review: Best Caravan 3G Signal Booster Under £150?](https://www.ukmobilebooster.com/en-gb/blogs/news/boost4u-cvgw-review-best-caravan-3g-signal-booster-under-150-in-the-uk) - [How to Boost Mobile Signal in Car UK: 7 Proven Methods](https://www.ukmobilebooster.com/en-gb/blogs/news/cvgw-how-to-boost-mobile-signal-in-car-uk-7-proven-methods-2025) - [Caravan Mobile Signal Booster UK: Complete Guide for Tourers](https://www.ukmobilebooster.com/en-gb/blogs/news/cvgw-caravan-mobile-signal-booster-uk-complete-guide-for-tourers-2025) Tags: 3G Car Mobile Signal Booster UK caravan mobile signal booster UK, vehicle signal booster UK, 4G car signal booster UK, mobile phone signal booster for car UK, caravan 3G signal booster UK, motorhome signal booster UK, EE O2 Vodafone Three all networks car booster, Dual Band 8 & 1 900/2100MHz vehicle booster UK best car mobile signal booster UK 2025, best caravan signal booster UK, buy car signal booster UK, cheap vehicle signal booster UK, 3G booster for caravan UK, EE car signal booster UK, O2 mobile signal booster for car UK, Vodafone in-car signal booster UK, Three car phone signal booster UK, mobile signal booster for motorhome UK, caravan mobile internet booster UK, plug and play car signal booster UK, vehicle signal booster with magnetic antenna UK, 365 day return car booster UK, free shipping caravan booster UK how to boost mobile signal in car UK, how to get better signal in caravan UK, why is mobile signal bad in car UK, poor mobile signal in vehicle solution UK, do car signal boosters work UK, are in-car signal boosters legal UK Ofcom, what is the best 3G booster for caravan UK, which network has best coverage on UK roads, how to install car mobile signal booster UK, car signal booster vs mobile hotspot UK, will a signal booster work in a moving car UK, how many bars can a car booster give UK, mobile signal booster for multiple devices in car UK, best position for car antenna booster UK, how to boost signal in static caravan UK best car signal booster UK comparison, weBoost Drive vs SureCall vs Boost4U CVGW UK, Boost4U CVGW review UK, car signal booster under 150 pounds UK, cheap vs expensive car signal booster UK, car booster vs caravan booster UK, mobile signal booster for car vs home UK, EE car booster vs O2 car booster vs Vodafone car booster UK, which car booster works with all UK networks, car signal booster with 5 bar guarantee UK, top rated vehicle signal booster UK 2025, caravan signal booster buyer guide UK, signal booster for boat UK vs caravan UK, mobile signal booster for van UK, car antenna booster for rural driving UK 3G car mobile signal booster UK, caravan signal booster, vehicle signal booster EE O2 Vodafone Three all networks, Dual Band 8 & 1 900/2100MHz car booster, Boost4U CVGW ## Details - **Price:** 259.99 GBP - 287.56 GBP - **Vendor:** UKMobileBooster.com - **Type:** United Kingdom - **Tags:** application 3G Data & Voice Calls, application vehicle, frequency 900 2100MHz, gb gb, gb giffgaff, gb lebara, gb lycamobile, gb o2, gb sky, gb talkmobile, gb talktalk, gb tesco, gb vodafone, has_stock_countdown, provider giffgaff, provider Lebara, provider Lycamobile, provider O2, provider Sky Mobile, provider Talk Mobile, provider TalkTalk, provider Tesco, provider Vodafone, sale ## Variants | Variant | Price | Available | |---------|-------|-----------| | No | 259.99 GBP | In stock | | Yes | 287.56 GBP | In stock | ## Images - A mobile signal booster kit, including an external antenna, a cable with a connector, and a power adapter. 3G Car Mobile Signal Booster UK | Boost4U CVGW £259.99 - Before and after comparison of a phone with dropped calls and full signal strength on a scenic road.
