Connect the indoor antenna to the MS port. 2. Connect the outdoor antenna to the BS Port. 3. Install the outdoor antenna and keep a minimum vertical distance of 10 meters from the indoor antenna. 4. Point the outdoor antenna to the direction where you know there is possibly a higher signal strength from the base station. 5. Power on the booster and check the signal strength. 6. 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.

If your area has no 800 & 1800 MHz 4G, coverage will be limited. - **100 m² max coverage:** Suitable for one room or a small flat; larger homes need the 300 m² or 500 m² models or an extended antenna kit. - **Requires at least 1 bar outdoors:** A booster cannot create signal where none exists — the outdoor antenna must receive a usable signal from the nearest mast. - **Standard cable is 5 m:** Homes needing the antenna on the roof may require the 110 m cable upgrade (£30.99). - **No built-in LCD / signal meter:** Unlike premium units, the CD100 uses LED indicators only — fine for most users but less precise for optimisation. - **Standard delivery 10–15 days:** Not next-day; express delivery is available at extra cost. ## How the CD100 Works The CD100 is a bidirectional RF repeater. It follows a three-step signal path: 1. **Capture:** The outdoor omni antenna picks up the weak 800 & 1800 MHz 4G LTE signal from the nearest mobile mast. 2. **Amplify:** The booster unit filters and amplifies both downlink (tower-to-phone) and uplink (phone-to-tower) signals by uplink ≥45 dB; downlink ≥50 dB. 3. **Redistribute:** The indoor whip antenna rebroadcasts the amplified signal throughout the 100 m² coverage zone, and relays phone signals back to the mast. ## Installation Steps (10–15 Minutes) 1. Find the strongest outdoor signal spot (usually near a window or on the roof) using your phone's signal bars. 2. Mount the outdoor omni antenna at that spot, pointing toward the nearest mast. 3. Run the 5 m coaxial cable from the outdoor antenna to the booster unit inside. 4. Screw the indoor whip antenna onto the booster unit. 5. Plug in the 12 V power adapter. The LED indicators will show power and signal status. 6. Wait 30–60 seconds for the booster to sync with the network, then test signal bars on your phone indoors. ## Frequently Asked Questions (10 Real UK User Questions) ### 1\. Does the CD100 work with 5G? No. The CD100 is a 4G LTE Dual Band 20 & 3 (800 & 1800 MHz) booster only. It does not amplify 5G frequencies (700 MHz n28, 3.5 GHz n78, etc.). However, 4G LTE remains the primary voice and data layer for most UK users, and VoLTE calls work perfectly. For 5G boosting, consider a multi-band 5G booster. ### 2\. Will this booster work with my specific network — EE, O2, Vodafone or Three? Yes. All four major UK networks use Dual Band 20 & 3 (800 & 1800 MHz) for 4G LTE coverage, especially in rural areas. The CD100 is compatible with EE, O2, Vodafone, Three and every MVNO running on those networks (giffgaff, Tesco Mobile, Lebara, Lycamobile, Plusnet, ASDA Mobile, SMARTY, iD Mobile, BT Mobile, Vectone Mobile). ### 3\. How many square metres does the CD100 cover? The CD100 covers up to 100 m² (approximately 1,076 ft²), which is typically one large room, a small flat or a home office. Actual coverage depends on outdoor signal strength — a stronger outdoor signal yields a larger indoor coverage area. For homes larger than 100 m², consider the 300 m² or 500 m² models or add the extended antenna kit. ### 4\. Is a mobile signal booster legal in the UK? Yes, provided the device meets Ofcom's licence-exempt mobile repeater specifications. The CD100 is UKCA / CE certified and operates within Ofcom's Technical Standard for Mobile Repeaters (2024), which permit licence-exempt use of repeaters that meet strict power and filtering limits. Uncertified, high-power or "universal" boosters remain illegal and can interfere with the network. ### 5\. Do I need an outdoor signal for the booster to work? Yes. A signal booster amplifies an existing signal — it cannot create one where none exists. You need at least 1 bar of usable 4G LTE (Dual Band 20 & 3) signal at the outdoor antenna location. If you have zero bars outdoors even with the antenna mounted high, a booster will not help and you should contact your network operator about a femtocell or network upgrade. ### 6\. How long does installation take and do I need an engineer? Most customers install the CD100 in 10–15 minutes without any tools or professional help. The kit includes everything needed: booster, indoor antenna, outdoor antenna, 10 m cable, power adapter and mounting bracket. Only basic DIY is required. If you need the antenna on a high roof or have a listed building, a professional installer may be advisable. ### 7\. Can multiple people use the boosted signal at the same time? Yes. The CD100 supports 10 simultaneous users and devices. There is no per-device cap — the whole household or office can make calls, stream video and browse simultaneously. Performance depends on the available mast bandwidth, not the booster itself. ### 8\. What is the difference between the CD100 and more expensive boosters? The CD100 is a dual-band (Dual Band 20 & 3 only) booster optimised for the UK's most widely deployed 4G frequency. More expensive units (£250–£600) typically offer multi-band support (3G + 4G + 5G), larger coverage (300–500 m²), built-in signal meters and app-based monitoring. For users who only need 4G LTE in a space up to 100 m², the CD100 delivers equivalent core performance at a fraction of the cost. ### 9\. What is the return policy and warranty? The CD100 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 - [Boost4U CD100 Product Page — £185.99](https://www.ukmobilebooster.com/products/cd100-mobile-booster) - [Best Mobile Signal Booster UK 2025: Top 5 Compared (CD100 Ranked #1 Budget)](https://www.ukmobilebooster.com/en-gb/blogs/news/cd100-best-mobile-signal-booster-uk-2025-top-5-compared-tested) - [Boost4U CD100 Review: Best Budget 4G Signal Booster Under £150?](https://www.ukmobilebooster.com/en-gb/blogs/news/boost4u-cd100-review-best-budget-4g-signal-booster-under-150-in-the-uk) - [How to Boost Mobile Signal at Home UK: 7 Proven Methods (2025)](https://www.ukmobilebooster.com/en-gb/blogs/news/cd100-how-to-boost-mobile-signal-at-home-uk-7-proven-methods-2025) - [Are Mobile Signal Boosters Legal in the UK?
