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 elerhent)
antenna
should be used.
NOTE:
Consult your dealer as to the selection and actual installation of the
FM antenna.
FM ANTENNA
CONNECTIONS
There are two ways of connecting the FM antenna to the
antenna input terminals: with a 300-ohm twin-lead feeder or
with a 75-ohm coaxial cable. If full justice is to be done to the
tuner's performance, a 75-ohm coaxial cable is recommended
since itis more immune than the twin-lead feeder to noise and
interference from external sources.
If an FM antenna
has
already been erected outdoors, connect it, referring to the
figure.
GROUNDING
Grounding is recommended if reception of FM programs is im-
paired by noise. To ground, connect a thick polyvinyl 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.
OUTDOOR AM ANTENNAS
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
If 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 out-
door AM antenna.
