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.
Grounding is recommended if reception of FM programs is impaired by
noise. To ground, connect a thick polyviny!-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.
CAUTION:
Never connect a wire to a gas pipe for grounding since sparks may ignite

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: 17—20 feet) 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 outdoor
AM antenna.
