HINTS FOR BETTER RECEPTION
OUTDOOR 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 multielement (3-, 5-, or 7-element) antenna should
be used.
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
Ifit 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.
