How Does 4G Mobile Phone Signal Booster Dual Band Works?
The external aerial antenna in this 4G indoor mobile signal booster
takes the existing weak signal from the mobile tower.
The 800/1800 MHz amplifier enhances the signal and sends it to the internal antenna.
The internal antenna then pushes out a full-strength signal inside the property this mobile signal booster is installed.
The installation process is very easy and simple.Follow step by step the instructions guide. Usually, it just takes a few minutes to set it up.
Please read the instructions properly before the purchase, as you may need to purchase additional items for the 4G signal enhancer installation. Check our easy installation guide here.
The Picture shows the upgraded LPDA antenna. This antenna is not included unless you pay to upgrade it. If you have a weak 1-2 bar signal, you need to upgrade to LPDA antenna. This will guarantee the unit to work to its full potential. This is CE-certified product and completely legal to use in the UK for both personal and commercial purposes as per Ofcom’s guidelines.

Technical Specifications
Frequently asked questions
Yes. Mobile signal boosters don’t rely on your Wi-Fi at all. They only grab the outdoor mobile signal and amplify it indoors. So even if your home broadband drops out, your calls, texts, and mobile data will still run fine through the boosted mobile signal.
Absolutely not. Once your booster is correctly installed, it does its job in the background without you having to do anything. Occasionally, you can check the cables or look at the antennas to ensure everything is secure. Other than that, you won't have to do anything.
Yes, they do. In many cases, basements and thick walls block signal, making it hard to stay connected. With a booster, however, the outdoor signal is captured and pushed inside. Hence, you can enjoy strong and steady coverage even behind thick walls.
Yes, there are different types of boosters available. You can find 4G signal boosters designed specifically for 4G coverage, 5G signal boosters built for 5G, and there are also boosters that support both 4G and 5G at the same time.
Choosing the right one depends on what coverage you currently have and what you want to prepare for in the future. If you want future-proof connectivity, a dual 4G and 5G signal booster is the best option, but always check the specifications to make sure the model supports both networks.
That really depends on the model you choose. Smaller boosters are designed for lighter use and can typically cover a flat or a couple of rooms, usually up to about 300 square metres.
Larger boosters, on the other hand, can handle much more space. These can cover an entire household or even bigger properties, ranging anywhere from 1,000 to 5,000 square metres. For offices, warehouses, or multi-floor buildings, you may need a booster with wider area coverage.
So, it all comes down to the size of the space and how strong you want the signal throughout.
Mobile signal boosters for home use are so simple to install and do not require any special skills. You just place the outdoor antenna on your roof or a wall where the signal is strongest, run the cable to the booster unit inside the building, and then plug it in. The key step is making sure the outdoor antenna is positioned where it can capture the best possible signal.
Some boosters are designed for one specific network, while others can handle multiple networks at once. A multi-network booster is especially useful if people in your home are on different providers like Vodafone, EE, O2, or Three, since everyone can benefit from the same device.
Yes, all our mobile signal boosters are safe to use in the UK, but only if they meet official network standards. The cheap ones you often see online from unreliable sellers can interfere with mobile networks and actually make things worse for you and anyone nearby.
Our boosters are fully compliant and built to work safely with all UK networks.
Not really. A signal booster is not technically a signal generator, it is more of an amplifier. It amplifies whatever mobile signal you can find outside so you can use it indoors. If there is absolutely no signal at all, then your booster will have nothing to work with.
Absolutely! Poor mobile signal also affects smart home devices like security cameras, video doorbells, smart thermostats, and IoT sensors that often rely on mobile data connections as backup when WiFi fails or for remote monitoring when you're away.Our indoor signal amplifiers strengthen the mobile data connection these devices depend on, ensuring your smart home ecosystem stays reliably connected and responsive.
Yes, most of our mobile signal boosters are designed to be relocatable, making them a smart long-term investment.The system components can be carefully removed and reinstalled in your new property, provided the new location has similar coverage requirements. However, it's important to note that these are stationary systems designed for fixed installation - they cannot be used while travelling or on the move.Once relocated and properly reinstalled in your new home, you may need to adjust the positioning of the external antenna and internal coverage units to optimise performance for your new property's layout and local signal conditions.
Yes, our mobile signal boosters are designed to support multiple devices and users simultaneously.Our Universal boosters are particularly effective in mixed-use environments where different people use various UK networks, ensuring everyone experiences improved signal strength and faster data speeds throughout the coverage area.
A mobile signal booster captures weak mobile signals from outside your building, amplifies them, and redistributes the stronger signal throughout your indoor space.If you're experiencing dropped calls, slow data speeds, or complete dead zones in your home or office, a mobile signal booster can significantly improve your mobile reception and provide reliable coverage even in areas where signals struggle to penetrate walls and building materials.
Our mobile signal boosters are designed to be extremely energy-efficient. In fact, you might actually save money because your devices won't be constantly searching for a signal, which drains their batteries much faster and requires more frequent charging. The improved efficiency of your mobile devices often offsets the minimal power consumption of the booster itself.
