how it work

1. Receives Signal

The powerful antenna reaches out to access a good signal, and delivers it to the booster.

2. Boostes Signal

The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.

3. Broadcasts Signal

Your devices get increased cell reception, and calls and data are fed through the booster back to the network.

how to install

Step 1:

Find a position where could receive great signal,mostly a higher position, like at rooftop. Install outdoor antenna at it and make it toward the base station.

Note: the outdoor antenna shall receive good signal, otherwise the repeater could not work.

Step 2:

Connect outdoor antenna to booster at BTS connector with the cable.

Step 3:

Connect indoor antenna to booster at MS connector. And it would be better to install it at a height of 2 meters.

Note: The two antennas shall be totally separated by a brick wall with a distance of at least 10 meters. Otherwise, the signal would intervene to each other, showing full of signal on display, but actually the booster doesn't work properly.
