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 the 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 design of the amplifier simplifies installation 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 Amplifier uses the coaxial cable to carry the TV/radio signal from
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 connection instructions carefully.

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, carefully 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 transformer (Cat. No. 15-1140) at the antenna.
• Follow the connection labeling on the amplifier/DC block unit: TO ANTenna, TO POWER
INJECTOR. The amplifier will not receive power if they are reversed.
• Follow the connection labeling on the power injector: TO TV, TO AMPLIFIER. Your TV/radio
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 use connection adapters or make a special cable.

ONE ANTENNA/TWO RECEIVER SYSTEMS
If you are using a single antenna with two TV/radio receivers, “Installation B” shows the proper
connections. To avoid damage to your TV/radio receivers and/or the amplifier power injector,
carefully check all the points listed below.
• For the first antenna and TV/radio receiver (#1), follow all instructions on Page 5 for “One
Antenna/One Receiver Systems.”
• Make sure the power injector is between the amplifier and the splitter (before the signal is
split).

Additional Amplification
If additional amplification is needed, you can connect another amplifier in line with the first amplifier. Remove the DC block from the optional second amplifier. One power injector will supply
enough power for both amplifiers.
Note: The In-Line Coaxial Amplifier can only be purchased as a kit, with the Power Injector and
DC Block. If you want to use a second amplifier in your system, retain the extra parts for future
additions to your system or as replacements if other parts are damaged or lost.

AMATEUR TV SYSTEMS
You can use the In-Line Amplifier with 2.4 GHz, amateur TV (ATV) systems, as shown in “Installation C.”
If the power supply provided with your ATV antenna provides a center-positive power supply, it
can be used to power the In-Line Amplifier as well; you do not need the amplifier’s power injector.
Caution: The In-Line Amplifier cannot be used if the ATV power supply is center negative.
In this case only, you should remove the DC block from the amplifier and connect the amplifier
directly to the F-type connector on the ATV antenna down converter. Remove the plastic tube
that holds the amplifier and DC block together and unscrew the two pieces.
If the ATV antenna is used with more than one TV receiver, you must follow all connection procedures for “One Antenna/Two Receiver Systems” (Page 7–9), except that the DC block between the antenna and the amplifier will be removed, as described above.

PROBLEM SOLVING
If the TV/radio receiver does not operate correctly after installation of the In-Line Amplifier:
• Immediately unplug the power injector.
• Check all connections and compare them with the appropriate installation drawing(s) in
this manual.
If no problems are found in the connections: Plug in the power injector and try the TV/radio
receiver again. If possible, try a different TV/radio receiver with the system or try the TV/radio
receiver with a different antenna system.
If the above procedures do not resolve the problem: Take the unit to your local RadioShack store for assistance.
