Grand Cherokee 4WD V8-4.7L VIN N (2000)
Antenna, Radio: Description and Operation
All models use a fixed-length stainless steel rod-type antenna mast, installed on the right front fender of the vehicle. The antenna mast has a spiral groove
cut down its length 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 receiver chassis.
The antenna coaxial cable has an additional disconnect, located near the passenger side cowl side inner panel behind the lower instrument panel
reinforcement. This additional disconnect allows the instrument panel assembly to be removed and installed without removing the radio receiver.
The factory-installed Electronically Tuned Radios (ETR) automatically compensate for radio antenna trim. Therefore, no antenna trimmer adjustment is
required or possible when replacing the radio receiver or the antenna.
