ANTENNA AND
GROUND CONNECTIONS
FM ANTENNA
FM
broadcast
sigr-rals
are
obstructed somewhat by mountains,
buildings and other obstacles. Therefore, even
if
a station
is
nearby,
a
high-gain antenna
may be
required. Select
the
antenna
in
accordance
with
the following
rules:
o If
the
receiver
is
to
be located
in
a
wooden building
and
stations are nearby, use the T-type antenna which
comes
with
the
SX-424. As shown
in
Fig. 5, connect the
feeder
wires
of
the
antenna
to the FM
antenna terminals.
Stretch
out the
antenna
proper
and secure
it
to the
ceiling
or
a wall in
such
a manner that reception is optimum,
as
determined by listening to the station to
be
received. Refer
to FM
RECEPTION
on
page
8.
o If
orientation
of
the T-type
antenna does
not
eliminate
background noise, connect
an
outdoor antenna
to
the
antenna terminals shown
in
Fig. 6. Instead
of
a
special FM
antenna, a combination FM/TV antenna may be
used.
NOTES:
1.
A variety of FM
antennas are
available. Consult
your
deaier.
2.
ln
locations
adjacent
to
heavily
traveled streets, around factories,
or
near
high voltage power transmission lines,
use
of
an FM antenna
may not give the
desired noise attenuation.
I
n
such
cases, consult
your
dealer concerning a cable feeder
(754) for
the
FM
antenna.
When coaxial cable is
used.
make connection
to
the
receiver
as
shown
in Fig
7
AM
ANTENNA
o
Refer
to AM
RECEPTION on page 8. With
an
AM station
tuned in, position the ferrite
antenna
for
optimum
recep-
tion.
See
Fig.
8.
. If
proper positioning
of
the ferrite antenna
does
not
give
satisfying results, stretch out the AM
lead antenna (vinyt-
insulated wire) and connect
it to
the AM antenna terminal.
Keep
the other
end
of the
antenna lead
as
high
as
possible.
r
If
the lead antenna
does
not give
satisfying results, erect
an
outdoor
antenna and connect
it
as
shown
in
Fig. 6.
No
special construction is required:
vinyl-insulated wire may
be
stretched between two
masts
or other
supports.
GROUNDING
o A
ground lead is
not
really required
for
reception. Still,
from
the viewpoint of safety and elimination of noise,
one
should be used.
