ANTENNA AND
GROUND CONNECTIONS
FM
ANTENNA
FM
broadcast signals are attenuated 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:
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-525. As shown
in
Fig. 5, connect the
feeder
terminals
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 pickup is optimum,
as
determined
by
listening
to
the
station
to
be
received.
Refer
to
"FM
Reception"
on
page
8.
. If
.orientation
of
the T-type
antenna does
not
eliminate
background noise, connect an
outdoor antenna
to
the
antenna
terminals shown
in
Fig. 6. In lieu of an antenna)
a
combination FM/TV antenna may
be used.
NOTES: 1. A
number
of
FM
antennas are available. Consult
your
sales
dealer
for
selection.
2. ln
location adjacent
to
heavily traveled streets,
around factories,
or
near
high-voltage power transmission lines,
use
of an
FM
antenna
may not give
the
desi
red
noise
attenuation.
ln
such
cases,
consult
your
sales dealer concerning a coaxial cable feeder
(75,f2)for
the
FM antenna
When coaxial
cable
is
used, make connection
to
the
receiver
as
shown
in
Fig. 7.
AM ANTENNA
Refer
to "AM
Reception" on
page 8. With an AM station
tuned
in,
position the ferrite antenna for optimum
pickup.
See
Fig.8.
If
positioning
of
the ferrite
antenna does
not yield
satisfy-
ing results, stretch out
the AM lead antenna (vinyl-insulated
wire)
and connect
it
to
the
AM
antenna
terminal. Keep the
other end of the antenna lead
as
high
as
possible.
If
the lead
antenna does
not
give satisfying results, erect
an
outdoor
antenna and connect
it
as
shown
in Fig. 6.
Special
construction is
not
required: vinyl-insulated wire may
be
stretched between two
masts
or other supports.

GROUNDING
o A
ground lead may
not
be
necessary
for
reception. Still,
from
a viewpoint
of
safety and elimination
of
noise,
one
should be
used.
