System Test - Antenna

ANTENNA TEST
Unplug antenna lead-in at back of radio and plug a test antenna into radio. Make sure test antenna base is grounded to the vehicle chassis. Do not touch the mast. Check radio reception in an area away from tall buildings, metal structures, power lines, fluorescent lighting and power tools. Tune to high and low ends of the dial on both AM and FM, checking weak and strong station reception. If reception is good and noise is eliminated, a problem exists with the original antenna and/or lead-in cable. To determine whether the antenna or the lead-in is faulty, perform the resistance check below. If the reception is still poor, the problem is not in the antenna.
