- The switch on the RF amplifier enables the AGC function. If the AGC is disabled then the amplifier gives maximum gain.
- MGC: The RF gain of the CBDA can be reduced by about 15 dB using the continuos trimmer on the amplifier. The RF gain is at maximum when the trimmer is at counter-clockwise direction. To reduce the gain, turn the trimmer clockwise using a screwdriver. Tur
- The AGC and MGC functions for the uplink path are reached by opening a small cover located on the DBA side adjacent to the Mobile antenna port. For the downlink path the window is located on the side near the Base antenna port.

RF Exposure Warning
In order to satisfy the FCC RF exposure requirements, you must ensure that the installation complies
with the following:
One antenna is connected via cable that has typical 1~10 dB attenuation (depends on the length of the
cable) to the CBDA BASE port. This antenna is installed outdoor and has very sharp beam (Yagi type or
similar) pointed to the donor (BTS). This type of antenna has about 10 dBi gain. Typical specifications:
gain: 8 dBd (=10.1 dBi), VSWR: better than 1.5:1 , Impedance: 50 ohm. The outdoor antenna must be
installed to provide a minimum separation distance of 0.5 m (50 cm) from persons within the area.
The second antenna is connected via cable that has typical 1~10 dB attenuation (depends on the length
of the cable) to the CBDA MOBILE port. This type of antenna is omni-directional (isotropic), or wide
beam, with 0 to 2 dBi typical gain and is installed and distributes indoor (in buildings, tunnels,
basements, park lots, shopping centers etc.). Typical specifications: gain: 2 dBi, VSWR: better than 2:1 ,
Impedance: 50 ohm. The indoor antenna must be installed to provide a minimum separation distance of
0.2 m (20 cm) from persons within the area.
