Routing the Cellular Antenna Cable
The Magnetic Cellular antenna has an integral antenna cable with a
TNC-M connector. The Bulkhead Cellular antenna has a 5-m (16 ft.)
integral antenna cable, which is terminated within the FME connector.
After routing the Bulkhead Cellular cable, the cable must be fitted
with a TNC (plug) connector, before attaching the cable to the
CrossCheck CDPD. Instructions for installing the TNC connector are
included with the antenna kit.
The next step in the installation process is routing and connecting the
antenna cable to the CrossCheck CDPD. When routing the cable, start
at the antenna and choose the most direct path to the
CrossCheck CDPD while avoiding the following hazards:
• Excess coils in the antenna cable, particularly the cellular
antenna cable. A coiled cable can act as an antenna and may
receive interference.
• Pinching the cable in a hinged door. Provide an adequate service
loop when routing the cable around vehicle hinges.
• Vehicle movement that might cause cable damage. Make sure
that the coax cable is not routed through areas where vehicle
movement can abrade the cable surface.
• Exposure to environmental damage. If your cellular antenna
cable is exposed to the environment, use tie wraps to secure the
cellular antenna cable along its route to prevent wind damage.
The Magnetic Cellular antenna cable is exposed to the
environment. Since the wind could cause the cable to whip
around, tie wraps should be used to secure the cable along
its route.
