The RadioShack 10 dB Coaxial In-Line Amplifier brings to your home video system the same
technology that is used in commercial cable systems: a single, standard coaxial cable carries
both the TV/radio signal and the power necessary for t he in-line amplifier .
The In-Line Amplifier reduces or eliminates the signal losses caused by signal transformers,
signal splitters, other in-line devices or extremely long cable runs between the antenna and receiver system. And, the In-Line Amplifier will amplify virtually any TV/radio signal, from 5 MHz
to 1 GHz (1000 MHz).
The compact, in-line desi gn of the amplif ier simplifies installati on at the “head end” of an antenna system (the end nearest the antenna, where amplification will do the most good).
The In-Line Amplifier can be used with antenna systems for:
• Standard VHF/UHF/Cable TV
• Amateur TV Systems
• Scanners
• FM Stereo Radio

Caution: Because the In-Line Ampli fier uses the coaxia l cable to carr y the TV/radio si gnal fr om
the DC power supply, proper connections are crucial. Failure to exactly follow the connection
instructions in this manual can result in damage to your amplifier or your TV/radio receiver.
ILLUSTRATION
Note: The amplifier and DC block are sealed together by a plastic tube. In most installations,
they must remain together. Read all connecti on instructions caref ully.

ONE ANTENNA/ONE RECEIVER SYSTEMS
If you are using a single antenna with a single TV/radio receiver, “Installation A” shows the
proper connections. To avoid damage to your TV/radio receiver and/or the amplifier power injector, careful ly check all the points listed below.
• Do not separate the amplifier from the DC block. The DC block must be between the
amplifier and the 300-to-75 ohm transforme r (Cat. No. 15-1 140) at the antenna.
• Follow the connection labeling on the amplifier/DC block unit:
INJECTOR. The amplifier will not receive power if they are reversed.
• Follow the connection labeling on the power injector:
receiver will be damaged if they are reversed.
• If a VHF/UHF splitter is used for a TV, it must be connected between the TV and the power
injector.
The In-Line Amplifier is designed for use with F-type connectors. For some antenna systems
(for scanners, for example), you will have to us e connection adapters or make a spec ial cable.
