    How it works

    how a cell phone booster works
    1 - Outdoor antenna

    The outdoor antenna receives and transmits signal to nearby cellphone towers. Outdoor antennas can be either directional or omni-directional.

    2 - Cellular amplifier

    The amplifier (or "repeater") boosts the signal coming to and from and going to the cell phone tower. The "gain" of the amplifier describes how strong the amplification is - you'll see that word scattered across our product pages.

    3 - Indoor antenna

    The indoor antenna rebroadcasts the signal inside the building. Some kits have more than one indoor antenna to help distribute the signal.


    The coverage area you can expect from any signal booster kit depends on the signal strength outside the building.

    Outdoor Signal Estimated coverage area
    Strong outdoor signal (5 bars) up to 6,000 sq. ft. coverage
    Medium outdoor signal (3-4 bars) up to 4,000 sq. ft. coverage
    Weak outdoor signal (1-2 bars) up to 2,000 sq. ft. coverage
    Note on Yagi antenna:

    If you use a yagi outdoor antenna, you can expect a 1.5x greater coverage area. However, you should expect to only improve coverage for one network. Read more about outdoor antennas here.
