EXTERNAL FM ANTENNA
The main advantage
of FM over AM is the quality of the broadcast signal. In order to benefit fully from the high signal quality of
FM broadcasts,
it is recommended
that a special-purpose
FM antenna be installed.
In weak signal areas, a multi-element
(3 element, 5 element,
7 element,
etc.) antenna should be used.

FM OUTDOOR ANTENNA CONNECTIONS
There are two ways of connecting
the FM antenna to the antenna
input terminals:
with a 300 _t twin-lead
feeder or with a 75
coaxial cable.
To get the most from the receiver performance,
a 75 _ coaxial cable is recommended
since it is more immune than the twin-lead
feeder to noise and interference
from external
sources.
