Antenna: Description and Operation
SYSTEM OPERATION
All models use a fixed-length stainless steel rod-type antenna mast, installed at the right front fender of the vehicle. A plastic sleeve is installed
over the length of the mast to reduce wind noise.
The antenna mast is connected to the center wire of the coaxial antenna cable, and is not grounded to any part of the vehicle. To eliminate static,
the antenna base must have a good ground. The coaxial antenna cable shield (the outer wire mesh of the cable) is grounded to the antenna base and
the radio chassis.
The antenna coaxial cable has an additional disconnect, located near the passenger side end of the instrument panel at the cowl side inner panel.
This additional disconnect allows the instrument panel assembly to be removed and installed without removing the radio.
The factory-installed Electronically Tuned Radios (ETRs) automatically compensate for radio antenna trim. Therefore, no antenna trimmer
adjustment is required or possible when replacing the receiver or the antenna.
