  • Test your outdoor signal in various places until you find a location of 4-5 mobile bars (full bar) or if not, then the best call quality you can get. This is the best place to mount an external antenna.
  • Be sure that the external antenna is a reasonable distance from other antennas like TV, if it is too close the signals from external antennas will interact with each other.
  • Select a convenient indoor place to install the booster and the interior antenna. We recommend the center of the ceiling in a room that needs a boosted signal so that the signal can cover each corner.
  • Always isolate the external and interior antennas from floors or walls, be sure they are not too close. If they are too close that causes breaks in the voice signals or calls cannot in or out.
  • The External antenna via cable connects to "BS" from the booster and interior whip antenna to "MS". Double check each connector, including connector below external antenna.
  • Mount base unit at place with good ventilation, if too hot not good for it work. More detailed installation information can be found at: If you have any questions, please don't hesitate let us know.

    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.

    Nick Baker (UK, Leeds)

    I am really happy that I decided to order a booster on 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!
