How It Works

1
The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster
2
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.
3
Your devices get increased cell reception, and calls and data are fed through the booster back to the network.
- Outside Antenna: Pulls in tower Signal.
- Signal Booster: Amplifies the Signal.
- Inside Antenna: Re-broadcasts Signal.
- Mobile Phone: Gets Boosted Signal.

Installation
- Mount external aerial on top back.
