BDA INSTALLATION PROCEDURE
IMPORTANT: DO NOT APPLY A.C. OR DC POWER TO THE BDA
UNTIL CABLES ARE CONNECTED TO BOTH PORTS OF THE BDA
AND THE ANTENNAS.
1. Mount the BDA on the structure with the RF connectors pointing DOWN. Using
appropriate screws and anchors, attach the BDA to the structure using the six mounting holes
on the side flanges.
2. Ensure that the isolation between the donor antenna and the service antenna is at least 12
dB greater than the BDA gain. (Use the higher of the Uplink and Downlink gains
reported on the BDA test data sheet).
3. Connect the cable from the donor antenna to the BDA connector labeled “BASE” and the
cable from the service antennas to the BDA connector labeled “MOBILE”.
4. Open the access door on the BDA and verify that the Uplink and Downlink ALC switches
are in their factory preset “ON” positions and attenuation is positioned to its maximum
setting.
5. Connect the AC power cord to the BDA and then to the power source. Turn the power
switch to its “ON” position. Verify that the “Power On” indicator is lit. Close the access
door.
Installation of the BDA is now complete. To adjust the gain controls to suit the specific
signal environment, refer to “BDA Operation”.
Note: For repeat installations of existing equipment, make sure the ALC switches are in
the “ON” position and attenuation is positioned to its maximum setting (30 dB). After
verification of ALC switches and attenuation, follow the above steps starting with step 1.
RF EXPOSURE WARNING
The antenna used for this transmitter must be fixed-mounted on outdoor permanent
structures. In order to satisfy the FCC RF exposure requirements, the BDA/antenna
installation must comply with the following:
The downlink indoor antenna (Omni type or similar directional antenna) must be installed so
as to provide a minimum separation distance of 0.35 meters (35 cm) between the antenna and
persons within the area. (This assumes a typical antenna with maximum gain of [2 dBi,
VSWR >?> 1.5:1, Zo= 50 ohms, and a cable attenuation of between 2-10 dB)
The uplink outdoor antenna (Yagi type or similar directional antenna) must be installed so as
to provide a minimum separation distance of 0.35 meters (35 cm) between the antenna and
persons within the area. (This assumes a typical antenna with maximum gain of [13 dBi,
VSWR >?> 1.5:1, Zo= 50 ohms, and a cable attenuation of between 2-10 dB).
