IMPROVING
FM
RECEPTION
If you have trouble with the
FM
recep-
tion
in
your area, try one of the ar-
rangements listed below.
Build the low-cost folded dipole
antenna illustrated (available at
your
local Radio Shack store). Attach the
flat cable to the 300-ohm terminals
on the receiver's back panel. You
can tack the antenna to the back of
a record cabinet
or
onto a wall.
Reception
is
usually best when you
attach the antenna at the highest
possible position.
A set of
VHF-
TV rabbit ears or anten-
nas made specially for
FM
reception
work
well
in
suburban areas. Connect
these types of antennas to the
300-ohm screw terminals
on
the
receiver's back panel.

An outside VHF-TV antenna provides
excellent FM reception. A "splitter"
(available at
all
Radio Shack stores)
permits you to connect a TV set and
your
receiver to the same antenna.
Your local Radio Shack store also
sells a full line of outside antennas to
help you achieve adequate recep-
tion
in
fringe areas.
If you use a 300-ohm flat cable, con-
nect it to the antenna's 300-ohm ter-
minals. If you use a 75-ohm coaxial
cable, connect it to the antenna's
75-ohm terminals. When you use the
75-ohm coaxial cable, attach the
center wire of the cable to the com-
mon terminal between the 75-ohm
and 300-ohm antenna terminals.
Then, connect the braided ground
wire under the clamp
as
shown
below.

Note: To protect your receiver, use a

CONNECTING A TURNTABLE
If your turntable has a magnetic car-
tridge, connect the turntable's output
jacks to the receiver's PHONO INPUT
jacks.
If your turntable has a ceramic or crystal
~artridge,
connect the turntable's output
Jacks
to the receiver's TAPE INPUT
jacks.
