RHBDA INSTALLATION
DO NOT APPLY A.C. POWER TO THE RHBDA UNTIL CABLES ARE
CONNECTED TO BOTH PORTS OF THE RHBDA AND THE
ANTENNAS.
1. Side the RHBDA into the 19” accessible rack. Mount the RHBDA to the rack. Using
appropriate screws, attach the RHBDA to the rack at the four mounting holes on the
Front panel.
2. Ensure that the isolation between the donor antenna and the service antenna is at
least 12 dB greater than the RHBDA gain.
(Use the higher of the Uplink and
Downlink gains reported on the RHBDA test data sheet).
3. Connect the cable from the service antennas to the RHBDA connector labeled
“MOBILE” and connect the cable going to the Base RF Signal Source to the RHBDA
connector labeled “UL OUT”, and the cable coming from the Base RF Signal Source
to the RHBDA connector labeled “DL IN”.
4. Verify that all attenuation settings are positioned at 30 dB.
5. Connect the AC power cord to the Rack Unit. Turn the power switch to the “ON”
position. Verify that each
Green
“Power ON” lamp, Laser alarms LED’s are
illuminated.
Installation of the Rack RHBDA’s 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 of the
attenuation, follow the above steps starting with step 1.
