RT and the RTCB, mounting the RT on the mast and aligning the RT.
Preparing RT Cable
The RT cable conducts all of the user traffic between the RTCB and the RT. The RT
cable also provides -48 VDC supply to the RT. The maximum length for one leg of
the RT cable is 100m (328 ft).

To prepare the RT cable:
1. Measure the distance between the RT and the RTCB along the assigned path.
2. Cut the required length of RT cable, allowing some spare length.
3. Assemble the DB-25 connector at the RTCB end of the cable, refer to

You can verify that the AirMux-104 units are aligned using the RSS/SNR, LINK and
STATUS LEDs located at the base of the RT. Alternatively, this can be done via the
AirMux management software.

Prior to connecting cables to the RT, the protective earth terminal (screw) of
the RT must be connected to an external protective ground conductor or to a
grounded mast.
Only a qualified person using the proper safety equipment should climb the
antenna mast. Only trained professional installers should be used when
installing or dismantling RTs and masts.
