2-36 Chapter 2: Installing the Hardware Infrastructure
Hanging an Antenna from a Roof Truss
Note: Maintain a minimum distance of 9.2 m (30 ft.) between a 1 W or
500 mW CBS's transmit and receive antennas. Minimum distance for a
100 mW CBS's transmit and receive antennas is 6.1 m (20 ft.).
To hang an antenna from a roof truss (or other object) refer to the
illustration on the following page and these instructions:
1. Screw the 0.61 m (2 ft.) threaded rod into the 1/4-20 UNC hole in
the back of the antenna.
Note: A 2 ft. threaded rod is supplied in the antenna kit. If the open
ceiling installation requires a longer section of threaded rod, it is
expected the requirement be pre-determined and the longer rod be
supplied by the installer.
2. Secure the antenna cable to the threaded rod using three equally
spaced cable ties.
Note: Attach the 0.25 m (10 in.) Receive antenna pigtail to a Receive
Antenna Cable before securing the cable to the threaded rod as shown
in the illustration.
3. In the desired location, hold the antenna cable against a roof truss
and lower the antenna to the desired height.
4. Use a cable tie to hang the antenna cable from the roof truss.
Caution: Antenna cables must be secured to a roof truss as shown in
the following illustration. Do not hang the antenna from a CBS's
connector as the connector cannot withstand the weight of the
threaded rod, cable, and antenna.
5. Connect the antenna cable to the CBS.
Note: Always connect the RX cable to the CBS before connecting the
cable to an RX antenna.
6. Use cable ties to secure the antenna cable.
