How it 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.

Strong outdoor signal (5 bars) up to 35,000 sq. ft. coverage
Medium outdoor signal (3-4 bars) up to 20,000 sq. ft. coverage
Weak outdoor signal (1-2 bars) up to 10,000 sq. ft. coverage
