If your power antenna mast ever becomes
damaged, the mast may not extend or retract
properly which might limit reception
performance. In this case, it is not necessary
to replace the entire power antenna assembly.
A replacement mast can be obtained from
your dealership for a nominal fee.
Occasionally, the power antenna mast should
be wiped clean with mild soap and water or
denatured alcohol. This prevents debris from
accumulating on the mast which can cause
excessive wear and decrease the power
antenna life. Never use petroleum-based
products to clean your antenna mast.
Common Radio Reception Conditions
Several conditions prevent FM reception from
being completely clear and noise-free, such as
the following:
1. Distance/Strength
The strength of the FM signal is directly related
to the distance the signal must travel. The
listenable range of an average FM signal is
approximately 25 miles (40 kilometers). Beyond
this distance, the radio is operating in a fringe
area and the signal becomes weaker.
2. Terrain
The terrain (hilly, mountainous, tall buildings) of
the area over which the signal travels may
prevent the FM signal from being noise-free.
