Antenna Port
The antenna port is a 50 Ohm female TNC. This line carries RF, signaling, and DC power for
the antenna. Note: Grounding the center conductor while power is applied to the transceiver
can cause the transceiver's fuse and/or a fuse in the vehicle to blow. No modifications should
be made to the RF cable under any circumstance
