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.
NOTE: Always make sure your antenna
(whether you have a power antenna or
a manually adjustable antenna) is fully
extended to its maximum length for
proper reception. If your antenna is not
fully extended, you may experience
signal loss while traveling in fringe
reception areas.
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.
If there is a building or large structure between
the antenna and station, some of the signal
"bends" around the building, but certain spots
receive almost no signal. Moving out of the
