4G Signal Booster: Enhance Mobile Coverage for Home, Office, Car

Possible Causes for Weak 4G Signals

Even though there are plenty of places where 4G service works, it is possible to suffer from bad cell phone reception for some specific reasons:

• Proximity to the cell tower – when you move away from the nearest cell tower, your phone’s reception becomes poor. [Ofcom Mobile Coverage Report].
• Building materials – concrete, steel frames, and energy-efficient windows can also reduce the strength of the mobile signal.
• Urban areas – tall buildings and heavy building density are likely to create signal shadows caused by the taller constructions blocking your ability to connect to the nearest cell tower.
• Natural terrain – if you are located on top of or behind a hill, in a valley, or amongst many trees, these objects will likely block your ability to connect to your nearest cell tower.
• Network congestion – location in an area of high density of users trying to connect to the same network causes a reduction in the amount of bandwidth available for you and the others trying to connect.
• Indoor dead zones – interactive basements, internal rooms, and large buildings have limited/no coverage.
• Signal interference – there may occur interference caused by other electronic appliances.

Knowing the cause of your signal problems will help you choose the right 4G mobile phone repeater to solve your particular problem.

Criteria for Choosing a Suitable 4G Repeater

• Network compatibility – Do you have coverage from your carrier? (i.e. Vodafone, O2, EE, Three, BT)
• Band frequencies – Does your operator use 800MHz, 900MHz, 1800MHz, 2100MHz or 2600MHz bands? You should identify which frequencies are supported by your carrier before selecting a booster.
• Gain (dB) – A higher gain level (65-75 dB) will provide you with better amplification if you are in a rural or difficult area. 
• Coverage area – The booster should be able to cover the area of your house/apartment/office (in square metres or square footage).
• Certificates – Boosters that are available to purchase in the UK/EU have to possess CE and RoHS certificates. 
• Antenna type & gain – The direction antenna can be utilized in the outdoor location for getting signals from a great distance; gain describes the quality of RF energy transmitted.
• Plug and play installation – Find an installation kit that possesses an LCD screen to set up your device within 30 minutes.

4G Aerial vs Antenna Boosters: Understanding the Terms

In the UK, you may see both "4G aerial booster" and "4G antenna booster" used to describe the outdoor signal-capturing component. They refer to the same hardware: a device that receives weak 4G signals from the nearest cell tower and passes them to your amplifier. Our kits include high-gain 4G aerial boosters compatible with all major UK networks.

• Directional aerials – Best for rural areas; focus on one distant tower for maximum gain.
• Omnidirectional aerials – Ideal for urban areas; capture signals from multiple directions where towers are closer.

All models are CE/RoHS compliant, support the most important UK carriers, and have a 3-year warranty.

What's Included in a 4G Booster Kit?

Each complete kit comes with all the tools you need for professional-grade installation:

• Aerial antenna (outdoor) to collect the strongest available cellular signal from the closest cell tower.
• Indoor/room antenna to broadcast the amplified incoming cell signal throughout your house or business.
• Amplifier unit – contains all functions required to operate the 4G wireless booster and has intelligent automated gain control and an LCD status display.
• Low-loss coaxial cables – connect the antennas to the amplifier to provide a minimal amount of signal attenuation between the antennas and the amplifier.
• Power supply & mounting hardware – all necessary brackets/fastenings to install securely.

Optional accessories: surge protector to prevent power surge damage, additional cable lengths, and high-gain directional antennas for challenging locations.

Simple 4-Step Installation Process

1. Find the best outdoor signal – Use the included signal meter or our mobile app to locate the strongest external signal point.
2. Mount the outdoor antenna – Place it on either a roof, wall, or chimney that has a direct view of the closest cell tower..
3. Connect the internal parts and install them. You have to connect the amplifier with the indoor antenna with a coaxial cable. There should be no fewer than 10 meters between the two antennas.
4. Plug in the amplifier, switch it on, and calibrate the gain levels with the help of the directions displayed on the LCD screen. In most plug-and-play setups, it does not take more than thirty minutes for you to calibrate the gain level.

Pro tip: Don't position the indoor antenna near any major objects, like a fridge, washing machine, either an electric oven or a range, and Wi-Fi routers as this might negatively impact the functioning of your device.
