Improving Fm Reception - Optimus STA-20 Owner's Manual

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.
