6. The booster system
Below diagram shows how simple and fast the booster system is installed and works effectively
One Yagi antenna, as donor antenna, is installed at the top of the roof to pick up good mobile signals from the
cell tower, and send through cable to the booster to amplify the signals significantly, and then the output signals
are transmitted into area by the indoor antenna. Very clear phone call or high speed mobile data are
immediately achieved within the area.
z Donor Antenna
：
¾ Outdoor panel or wide band Yagi is recommended.
¾ Function: Pick up outside signals from the cell tower and send to the repeater by cable; donor
antenna also transmits the uplink signals from the booster to cell tower.
z Server Antenna:
¾ Indoor Omni ceiling or indoor panel is recommended, whip antenna is also ok for 10dBm booster,
however the coverage size will be limited.
z Cables: LMR 300 or 400, 3D, 5D or 8D - FB coax cables are recommended.
z Splitters or couplers: when the building structure is too complicated or there is big loss due to thick
walls, etc., splitters or couplers shall be used so that more antennas can be installed in more areas
to distribute the signals to each corner of the coverage area.
