The outdoor antenna captures available cellular signal and delivers it to the booster unit.
The amplifier processes and strengthens the signal, acting as a relay between your devices and the cell tower.
Enhanced signal is distributed indoors, improving call quality and data connectivity.
Ensure your location has GSM 900MHz and WCDMA 2100MHz coverage with at least 2 bars of outdoor signal before installation. The repeater requires existing outdoor signal to improve indoor reception.
