Your RadioShack Amplified VHF
/
UHF
/
FM In-
door Antenna’s design includes a UHF direc-
tor/reflector for more precise UHF reception,
telescoping antenna elements for clearer
VHF/FM reception, and a fine tuning control.
The built-in amplifier boosts the received sig-
nals to your TV or FM receiver for the best
picture and sound.
Its features include:
Built-In Solid-State Amplifier
— boosts the
input signals by up to 30 times to deliver the
best possible signal to your FM receiver or
TV.
High/Low Gain Selector
— lets you select
the amount of amplification to match your
available signal.
12-Position Fine Tuning Control
— lets
you precisely tune the antenna to help elimi-
nate ghosting and graininess in the picture.
UHF Loop Antenna
— lets you easily tilt the
antenna 180° and rotate it 360° for the best
receiving angle for UHF channels.
Highly Conductive VHF/FM Dipole Anten-
nas
— extend to 39 inches in length and
swivel 360° for easy adjustment.
Warning:
This antenna is for indoor use
only.
CONNECTIONS
The antenna connects to your TV or FM re-
ceiver using the supplied 75-ohm coaxial ca-
ble.
Follow these steps to connect the antenna’s
output to your TV (or FM receiver).
1. Place the antenna on top of the TV (or
FM receiver) so it is close to the VHF
