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 7dbi outdoor panel or 9dBi wide band Yagi is recommended as donor antenna.
¾ Function: Pick up donor signals from the cell tower and send to the Booster by cable; the power
level and quality of the received signals influence a lot on the coverage effect. Donor antenna
also transmits the uplink signals from the Booster to cell tower.
z Server Antenna:
¾ 3dBi indoor Omni ceiling or 7dBi indoor panel are recommended, whip antenna is also ok for
10dBm Booster, however the coverage size will be limited.
¾ Omni antenna (Indoor ceiling omni antenna or whip antenna), suitable to be installed in the center
and radiate all direction; It is better to use a directional panel antenna or wide band Yagi when the
coverage shape is long and narrow (corridors, long row of houses in two sides, tunnels or
elevators or rural open space)
z Cables: LMR 300 or 400, 3D, 5D or 8D - FB coax cables are recommended.
z Splitters or couplers:
z 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 splitters or couplers shall be used so that more
