Wrangler 4WD L4-150 2.5L VIN P MFI (1998)
Antenna: Description and Operation
SYSTEM OPERATION
All models use a fixed-length stainless steel rod-type antenna mast, installed on the right front cowl side panel of the vehicle. 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 antenna coaxial 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 behind the right end of the instrument panel between the radio and the right cowl
side 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.
