BDA INSTALLATION
DO NOT APPLY A.C. POWER TO THE BDA UNTIL CABLES ARE CONNECTED TO
BOTH PORTS OF THE BDA AND THE ANTENNAS.
1. Mount the BDA on the wall with the RF connectors pointing DOWN. Using appropriate screws and
anchors, attach the BDA to the wall at the four 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 door of the metallic box of the BDA and verify that both of the PSU switches are in their factory
preset “ON” positions. Close the panels.
5. Connect the AC power cord to the BDA and then to the power source. Verify that
the “Power ON” lamp is illuminated.
6. Connect the computer with the software v1.02 installed via RS 232 connector or via a USB port.
7. on RF_BDA_GUI make sure that AGC Anable, ASD Enable and HPA Enable fuctions are turned ON.
Installation of the BDA is now complete. To adjust the gain controls to suit the specific signal environment,
refer to the section monitoring and Control.
