INSTALLATION: 

 

 
 
 
 
 
 
 
DO NOT APPLY A.C. POWER TO THE RHBDA UNTIL CABLES ARE 
CONNECTED TO BOTH PORTS OF THE RHBDA AND THE 
ANTENNAS.  

 
1. Set the BDA Rack 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 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. 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.
