How cell signal booster works ?
1.The outdoor antenna captures signal from the signal tower
2.The outdoor antenna transfers the signal to the cell booster via the Coaxial cable
3.The booster amplifies cell signal and sends it to the Indoor antenna
4.The Indoor antenna rebroadcasts the signal insides to all mobile devices
5.The Booster amplifies outgoing cell signal back to the signal tower
