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.

ONE ANTENNA/TWO RECEIVER SYSTEMS
If you are using a single antenn a wit h two TV/radio receivers, “I nstallation B” shows the prope r
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 S ystems.”
• Make sure the power injector is between the amplifier and the splitter (before the signal is
split).

Additional Amplification
If additional ampli fication is needed, you can connect another amplifie r in l ine with the first amplifier. Remove the DC block from the optional second amplifier. O ne power injector will suppl y
enough power for both amplifiers.
Note:
The In-Line Coaxial Amplifier can only be purchased as a kit, with the P ower Injector and
DC Block. If you want to use a second amplifier in your system , ret ain the extra parts for future
additions to your system or as replacement s 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 su pply provided with your ATV antenna provides a center-positive power supply, it
can be used to power the In-Li ne Am plifier as well ; you do not need the amplifier’s power injector.
Caution:
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 ante nna is used with more t han one TV receiver, you must follow all c onnection procedures for “One Antenna/Two Receiver Systems” (Page 7–9), except that the DC block between the antenna and th e amp li fi er will be removed, as described above.
The In-Line Amplifier cannot be used if the ATV power supply is center negative.

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:
receiver again. If possible, try a different TV/radio receiver with the system or try the TV/radio
receiver with a dif ferent antenna syste m.
If the above procedures do not resolve the problem:
dioShack store for assistance.
