Figure 5: External LED Indication and Manual Gain Attenuation Access
INSTALLATION
DO NOT APPLY A.C. POWER TO THE UNIT UNTIL CABLES ARE
CONNECTED TO BOTH PORTS OF THE BDA AND THE ANTENNAS.
1.
Set the BDA on the floor or mount on a wall (where applicable). Using appropriate screws
and anchors, attach the BDA to the wall at the four mounting holes on the side flanges.
(Special version not shown in this manual).
2. Ensure that the isolation between the base station antenna and the mobile antenna
should be at least 12 dB higher than the BDA gain (Use the higher of the Uplink and
Downlink gains reported on the BDA test data sheet).
Isolation less than this value can cause gain ripple across the band. Isolation equal to
or less than the BDA gain will give rise to oscillations which will saturate the amplifiers
and possibly cause damage to the BDA.
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. See main Panel of the BDA and verify that both of the Uplink and Downlink attenuation is
set to 30 dB via dial Attenuator.
5. Connect the AC power cord to the BDA and then to the power source. Verify that the
“Power ON” lamp is illuminated.
Installation of the BDA is now complete. To adjust the gain controls to suit the specific signal
environment, refer to the next section of the manual.
Note:
For repeat installations of existing equipment, make sure the attenuation is
positioned to its maximum setting (30 dB). After verification attenuation, follow the
above steps starting with step 1.
