(RTA) - Rx/Tx antenna connection
The Rx/Tx antenna connection is located on the rear right side of the VHF transceiver (see Section “Interface
connections” in the installation section). If you reach this section of the manual, it is because there are
identified problems with either the transmission of Voice/DSC or the reception of a voice signal. Antenna
conditions and antenna installations have been checked OK as well.
