Dakota 4WD V6-3.9L VIN X (1997)
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. The 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 chassis. The antenna coaxial cable has an additional disconnect, located near the inboard side of the glove box
opening on the back of the instrument panel, to allow instrument panel installation and removal without removing the radio.
The factory-installed ETRs automatically compensate for radio antenna trim. Therefore, no antenna trimmer adjustment is required or possible
when replacing the receiver or the antenna.
CIRCUIT OPERATION
