Cable-TV Amplifier

Selecting a Location
Select a location for your amplifier that is close to
your input source and an AC outlet. You can
mount the amplifier on a wall or other surface
using #6 screws (not supplied).
• Do not place the amplifier outdoors.
• To keep exposed cable to a minimum, you can
also place the amplifier in your attic.
• To prevent interference, do not place the
amplifier within six inches of any other
electronic device.
Routing Cables
Route 75-ohm (RG-6 or RG-6QS) coaxial cable from the amplifier to your
input source and receiver. Follow these hints when routing cable:
• Use only as much cable as is necessary to reach from the amplifier to
the input source and receiver.
• Do not route cables where they might be cut, crimped, or crushed by
normal activities.
• For the best appearance, route the cable through the attic and walls, and
terminate each cable in a wall mount box with an F-connector. Wall
mount F-connectors, coaxial cable, and other video accessories are
available at your local RadioShack store.

Making Connections
1. Connect a coaxial cable to your input source.
To connect more than one input source to the
amplifier, use a high isolation A/B switch or
video selector to switch between inputs.
2. Connect the coaxial cable from your cable box
or antenna (input source) to the amplifier’s
INPUT terminal.
3. Connect one end of a coaxial cable to your
output device (TV, cable modem)and the other
end to the amplifier’s OUTPUT terminal.
4. Connect the supplied AC adapter to the jack
on the amplifier.
5. Plug the AC adapter into a standard AC outlet.
