HINTS FOR BETTER RECEPTION
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)
antenna should be used.
FM OUTDOOR
ANTENNA
CONNECTIONS
To get the most from the receiver performance, a 75-ohm
coaxial cable is recommended since it is more immune than
the twin-lead feeder to noise and interference from external
sources. !f an FM antenna has already been erected out-
doors, connect it, referring to the figure.
GROUNDING
Grounding is recommended if reception of FM programs is
impaired by noise. To ground, connect a thick polyvinyl
insulated wire to the GND terminal and attach the other end
to a metal water pipe or grounding bar or wind it around a
copper plate and bury it.
NOTE:
Never connect a wire to a gas pipe for grounding since sparks
may ignite the gas.
EXTERNAL AM ANTENNA
If it is not possible to obtain adequate AM reception even by
changing the orientation of the AM loop antenna, a separate
indoor antenna, or an outdoor antenna should be installed.
INDOOR
AM
ANTENNA
Use a vinyl insulated wire (5—6 m) and connect one end to
the AM antenna terminal and affix the other end to the wall
or Ceiling, as high as possible.
OUTDOOR
AM ANTENNA
{f reception quality is not improved sufficiently even when
an indoor antenna is used, a vinyl insulated wire should be
installed outside and fixed in place.
NOTE:
Do not detach the AM loop antenna when using an indoor or an
outdoor AM antenna.
