I n t r o d u c t i o n
The RadioShack 1-4 Bi-Directional Cable-TV
Amplifier is ideal for distributing a cable signal to
a remote location. It can also distribute antenna
and HDTV signals. This amplifier increases the
output signal up to 8dB, while minimizing
interference. It also allows bi-directional
communication so you can enjoy pay-per-view
events and interactive TV. It is also compatible
with digital cable modems. The amplifier can be
mounted on a wall or placed on a table or other
indoor surface. You can cap off the unused
outputs with the supplied terminators to reduce
signal leakage.

Selecting a Location
Your amplifier should be placed 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) suitable for mounting in
your location.
• Do not place the amplifier outdoors.
• To keep exposed cable to a minimum, you can
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 to each receiver. Follow these hints when routing cable:
• Use only as much cable as necessary to reach from the amplifier to the
input source and receivers.
• Do not route cables where they might be cut, crimped, or crushed by
normal activities.
• For the best appearance, route 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.
