2.1 Antenna Coupler
Note: The T/R antenna is automatically connected to ground when the power is turned
off.
2.1.1 General connections
Three cables connect to the Antenna Coupler: the signal cable (7-core cable
(05S0952) or 5P cable (05S0793)), coaxial cable from the Transceiver Unit, and the
antenna wire.
For the connection of the antenna wire, use an insulator so as not to put stress on the
connector at the ANT terminal of the Antenna Coupler.
Note: For the 5P cable (05S0793), cut off the armor to pass the cable through the ca-
ble entrance on the Antenna Coupler, and then wrap vinyl tape around the end of ar-
mor.
