High Gain In-Line Signal Amplifier
Your RadioShack High Gain In-Line
Signal Amplifier increases the
strength of cable TV and VHF/FM signals up to 20 dB ! This amplification is
necessary when a cable TV signal
travels through a l ong length of cable
(100 feet or more) from the antenna or
cable outlet to the TV or VCR, or when
the signal is too weak to produce a
good picture.
Your amplifier also feat ures an adjustable gain control that lets you adjust
the amplification up to 10 dB if you
don’t need the full 20 dB. This control
helps prevent signal overload.
This amplifier is not recom-

MOUNTING AND
CONNECTING THE
AMPLIFIER
Use RG-6QS (Quad shield) 75-ohm
coaxial cable, available at your local
RadioShack store, for all amplifier
connections.
Note:
Use only the length of cable
necessary for the connections. Excess cable causes loss of signal
strength.

2. Connect the output terminal of the
cable box or VH F/FM antenna to
the amplifier’s
3. Connect the amplifier’s
OUT
terminal to the 75-oh m VHF
terminal on your TV or VCR. If
your TV has only 300-ohm VHF
terminals, use a 75-to-300 transformer (such as RadioShack Cat.
No. 15-1230).
4. Plug the amplifier’s power cord
into a standard AC outlet.

or cable outlet to the input terminal of an optional 75-ohm splitter
(available at your local
RadioShack store).
3. Connect the splitter’s output terminals to the amplifier’s
terminal and the input terminal of
the cable box.
4. Connect the amplifier’s
OUT
terminal to the 75-ohm V HF
terminal on the first TV or VCR.
Connect the cable box’s output
terminal to the 75-ohm VHF terminal on the second TV or VCR.
For a TV with only 300-ohm VHF
terminals, use a 75-to-300 transformer (such as RadioShack Cat.
No. 15-1230).

USING THE GAIN
CONTROL
Use the
signal overload. Common signs of signal overload are horizontal dark and
light bands or double images on the
screen.
At fully clockwise (+), the gain is 20
dB. This amplifies the signal by a factor of 100. To reduce the gain, turn the
control counterclockwise (toward –).
At fully counterclockwise, the gain is
about 10 dB.
