CBS Antennas
Two types of antennas are available:
• Transmit
• Receive
The transmit and receive antennas look similar, but have the following
differences:
• The transmit antenna has a small blue dot on the antenna case.
• The transmit antenna has a 1.83 m (6 ft.) cable attached. The cable
has a threaded reverse polarity TNC connector that attaches to the
CBS.
• The receive antenna has a 0.25 m (10 in.) cable attached. The cable
has a female BNC connector. A CBS Receive Antenna cable (1424-
C057-0180) is used between the attached cable and the CBS. This
cable has two BNC connectors.

Note: The new Antenna cable for Freezers is 6 meters (19 feet) long.
Note: With 100 mW CBSs, a 15 m (49 ft.) receive antenna cable
1416-C520-0150
must be used instead of the usual 18 m (59 ft.) receive
antenna cable.
Consider the following when installing antennas:
• Install the antennas at the same time that the CBSs are installed.
• When connecting cables to antennas (especially Transmit
antennas), make sure connections on both ends are properly
aligned on the threads and are screwed down completely.
• Use care when connecting cables so the antenna cable connector is
not loosened from the circuit board inside the antenna.
