Thank you for buying the RadioShack
Amplified AM/FM Antenna. It provides
excellent AM and FM radio reception so
you can listen to your favorite stations
through your home stereo or A/V receiver.
The built-in gain control boosts weak
signals and reduces feedback from strong
signals.
Connections
1. If your FM receiver has an F-connector,
connect the antenna's F-connector to your
receiver's FM antenna input terminal.
If your FM receiver has a 300-ohm twin-lead
connector, connect the supplied matching
transformer to the antenna's F-connector.
Then, connect the matching transformer's
twin leads to your receiver's FM terminals.
If your FM receiver has pushbutton terminals,
connect the supplied matching transformer to
the antenna's F-connector. Cut off the transformer leads, and strip

Positioning the Antenna
For best performance, place the antenna
indoors, as high as possible. Do not mount
the antenna near metal surfaces or other
obstructions, such as a refrigerator, a door
or wall, or a water pipe hidden behind a
wall.
Before mounting the antenna, you need to
determine where the clearest reception is
received.
1. Turn on your FM receiver, and tune it
to a station near 98 MHz.
2. Position the antenna as high as
possible at the desired mounting
location.
3. Slowly move the antenna until you
receive the clearest sound. Note the
location.
4. Tune your FM receiver to a station
near 88 MHz. Repeat Step 3 until you
receive the clearest sound. Note the
location.
5. Tune your FM receiver to a station
near 108 MHz. Repeat Step 3 until
you receive the clearest sound. Note
the location.
6. Use the locations noted in steps 2-5 to
mount your antenna at the location
with the best reception.
