AM STATIC NOISE ON VEHICLES WITH POWER ANTENNAS
Vehicles with power antennas may exhibit audible electrical noise on weak AM stations when various electrical accessories (turn signals, rear defogger,
cruise control, brakes, etc.) are operated.
Poor antenna grounding can cause this condition.
To eliminate or reduce the intensity of the noise, use the following repair procedure:
REPAIR PROCEDURE;
1.
Tune the radio to a strong, static-free AM station and slowly move the tip of the antenna mast forward and back approximately 2 inches (fig 1). If
static noise is not heard, go to Step 2. If static noise is heard during antenna movement, replace the antenna mast and go to Step 3.
NOTE:
Do not touch the antenna mast with your bare hands. Use a glove or nonmetallic object to move the antenna. (If you touch the antenna with your
hands, you will change the antenna sensitivity).
2.
Remove the antenna mast and inspect the base of the mast for corrosion and damage (fig 2). Clean with 1500 grit sandpaper.
