Amplified UHF/VHF/FM Indoor Antenna
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
terminal.

shock hazard, do not expose this product to rain

2. If your TV (or FM receiver) has an F-con-
nector:
a. Connect one end of the supplied
coaxial cable to your TV (or FM
receiver).
b. Connect the other end of the cable to
the antenna’s TO TV jack.
If your TV set (or FM receiver) does not
have an F-connector:
a. Connect one end of the supplied
coaxial cable to the F-connector in a
transformer/splitter (not supplied).
b. Connect the other end of the cable to
the antenna’s TO TV jack.
c. Connect the transformer/splitter’s
brown 300-ohm twinlead to your TV’s
(or FM receiver’s) VHF terminal
screws.
d. Connect the transformer/splitter’s
gold 300-ohm twinlead to your TV’s
(or FM receiver’s) UHF terminal
screws.
Cautions:
You must use a Class 2 power
source that supplies 12V DC
and delivers at least 100 mA.
Its center tip must be set to positive and
its plug must fit the antenna's 12VDC
100MA
jack. The supplied adapter meets
these specifications. Using an adapter
that does not meet these specifications
could damage the antenna or the
adapter.
• Always connect the AC adapter to the
antenna before you connect it to AC
power. When you finish, disconnect the
adapter from AC power before you dis-
connect it from the antenna.
3. Insert the supplied AC adapter’s small
barrel plug into the 12VDC 100mA jack on
the back of the antenna’s base.
4. Plug the AC adapter into a standard AC
outlet.

OPERATION
1. Set GAIN HIGH/LOW on the back of the
antenna’s base to HIGH for weak or dis-
tant stations. The red indicator on top of
the antenna’s base lights to indicate that
the antenna’s amplifier has power.
Set GAIN HIGH/LOW to LOW for strong or
nearby stations, or when you are not
using the antenna. The red indicator on
top of the antenna’s base turns off to indi-
cate that power to the antenna’s amplifier
is turned off.
2. For the best VHF (Channels 2–13) and
FM (88–108 MHz) reception:
a. Extend the telescoping antenna ele-
ments as follows:
b. Adjust the antenna elements outward
or inward and/or forward or backward
for the best picture and sound.
c. Turn the fine tuning control to one of
the 12 positions for the best picture.
3. For the best UHF (Channels 14–69)
reception, turn the UHF loop antenna left
or right and tilt it forward or backward for
the best picture and sound.
CARE
Keep the antenna dry; if it gets wet, wipe it dry
immediately. Use and store the antenna only
in normal temperature environments. Handle
the antenna carefully; do not drop it. Keep the
antenna away from dust and dirt, and wipe it
with a damp cloth occasionally to keep it look-
ing new.
Modifying or tampering with the antenna’s in-
ternal components can cause a malfunction
and might invalidate its warranty and void
your FCC authorization to operate it. If your
antenna is not performing as it should, take it
to your local RadioShack store for assistance.
