    How It Works

    how mobile phone signal booster work for home office


    Receives signal
    The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster


    Boosts signal
    The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.


    Broadcasts signal
    Your devices get increased cell reception, and calls and data are fed through the booster back to the network.

    Get up to 32x stronger signal


    1. 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.

    Quick delivery despite COVID-19 outbreak, get it in a couple of days.

    Nick Baker (UK, Leeds)

    I am really happy that I decided to order a booster on UKMobileBooster.com. Due to the pandemic of coronavirus, we have taken a decision to stay at home. But of course, in our case self-isolation could have presupposed full isolation from the whole world as the quality of our mobile signal at home used to leave much to desire.

    In home O2 signal booster is a perfect solution for small cottages.

    Mark Smith (UK, Wigston)

    I would recommend this booster to anyone, because it’s a really good option for small cottages, the price is very adequate, and the whole system itself is safe and compact. It doesn’t waste a lot of energy while it’s working, and turns off automatically when not used, and I noticed that it actually saves the battery of my phone.

    How I managed to solve my Vodafone mobile phone signal problems

    Peter Barrett (UK, Somerset)

    If you are fed up with mobile signal issues, try to use GBC100. We like it! I would definitely recommend this device (or other products of this seller) to anyone facing the same EE 4G signal problems in the UK. The device is really worth the price!
