station or behind
a ferroconcrete building where
the radio field strength is low, install an outdoors
FM antenna. The height and direction of the out-
door
antenna
should
be adjusted
for optimum
reception.
When
the distance between
the antenna and this
tuner is over 30 meters
(around
100 feet), or in
areas subject to heavy traffic or close to a high-
tension
power
line, noise may
disturb
listening
even when the FM exclusive antenna is sued.
However,
since the coaxial
cabJe is a 75
ohm
unbalanced"' type, install a matching transformer
between
the antenna
and
the coaxial
cable to
prevent
wave
loss. When
this conversion
trans-
former
is incorporated
tn the antenna, a normal
75 ohm coaxial cable can be used,
