5. Repeater system overview

The picture below shows how simple and fast booster installation is and how effectively it works.

A Yaggi or panel antenna (it depends on the booster model and its power), as donor/outdoor antenna, is installed at the top 
of the roof to pick up good mobile signals from the base station, and sends them through the cable to the booster where the 
signals get amplified significantly; and then the output signals are distributed throughout the area by the indoor/server 
antenna. Clear phone calls or high speed mobile data are immediately achieved within the area.

A repeater kit includes:

Outdoor Antenna

: 

Outdoor panel or wide band Yaggi is recommended. 
Function: To pick up outside signals from the base station and send them by cable to the repeater; outdoor antenna 
also transmits the uplink signals from the repeater back to the base station.

Indoor Antenna

It is mounted inside a building to transmit the improved signals throughout the coverage area.

Cables

: Сoaxial cables for indoor and outdoor antennas.

Mountings

: Special mountings for antennas and the booster (depends on a booster model)
