INTRODUCTION
The RadioShack Satellite/TV/FM In-Line Signal Amplifier brings to your home video system the
same technology that is used in commercial cable systems: a single, standard coaxial cable
carries the satellite, TV, radio signal and the power necessary for the In-Line Signal Amplifier.
The In-Line Signal Amplifier reduces or eliminates the signal losses caused by signal trans-
formers, signal splitters, other in-line devices or extremely long cable runs between the anten-
na and receiver system. The In-Line Signal Amplifier will amplify virtually any satellite, TV, or
radio signal, from 50 MHz to 2,200 MHz.
The compact, in-line design of the amplifier simplifies installation at the “head end” of an anten-
na system (the end nearest the antenna, where amplification will do the most good).
The In-Line Signal Amplifier can be used with antenna systems for:
• direct-to-home satellite
• standard VHF/UHF/cable TV
• amateur TV systems
• scanners
• FM stereo radio

Caution:
Because the In-Line Signal Amplifier uses coaxial cable to carry the satellite/TV/radio
signal from the DC power supply, proper connections are crucial. Failure to follow exactly the
connection instructions in this manual can result in damage to your amplifier or your satellite/
TV/radio receiver.
Note: You cannot insert splitters in the coax lead-in from the antenna to the power injector.

ONE ANTENNA/ONE RECEIVER SYSTEM
If you are using a single antenna with a single receiver, “Installation A” shows the proper con-
nections.
Caution: To avoid damage to your 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 at the antenna.
• Remove the DC block and the plastic tube that connects the DC block and the amplifier
when using with a satellite or powered antenna.

a special cable.

If you are using a single antenna with two TV/radio receivers, “Installation B” shows the proper
connections. To avoid damage to your satellite/TV/radio receivers and/or the amplifier power
injector, carefully check all the points listed below.
Note: Make sure the power injector is between the amplifier and the splitter (before the signal

ONE SATELLITE DISH/RECEIVER SYSTEM
Your In-Line Signal Amplifier can be used in a one-wire solution that allows you to combine the
direct-to-home signal from your satellite dish and the VHF/UHF signal from your TV antenna by
using a satellite signal splitter/combiner (not supplied) or a TV/satellite diplexer (not supplied).
See the connection in “Installation C.”
Combining the Outdoor Signal
Use a satellite signal splitter/combiner to combine the output of the In-Line Signal Amplifier’s
signal and the direct-to-home satellite signal in a single coaxial output lead. The satellite/re-
ceiver transfers power to the In-Line Signal Amplifier and the satellite dish’s LNB (Low Noise
Block) unit. See the connection in “Installation C.”
Splitting the Indoor Signal
Use a TV/satellite diplexer to separate the In-Line Signal Amplifier antenna signal and the di-
rect-to-home signal, then route them to the TV’s antenna input and the direct-to-home receiv-
er’s input. See the connection in “Installation C.”

AMPLIFIED ANTENNAS
You can use the In-Line Signal Amplifier with amplified antenna systems, as shown in “Installa-
tion D.”
If the power supply provided with your amplified antenna provides a center-positive power sup-
ply, it can be used to power the In-Line Signal Amplifier as well; you do not need the amplifier’s
power injector.
Caution:
The In-Line Signal Amplifier cannot be used if the amplified antenna 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 antenna. Remove the plastic tube that holds the amplifi-
er and DC block together and unscrew the two pieces.
If the antenna is used with more than one TV receiver, you must follow all connection proce-
dures for “One Antenna/Two Receiver Systems” on Page 8, except that the DC block between
the antenna and the amplifier will be removed, as described above.
Note: The In-Line Signal Amplifier is designed for use with F-type connectors. For some anten-
na systems (such as scanners, for example), you will have to use connection adapters or make
a special cable.

Additional Amplification
If additional amplification is needed, you can connect another amplifier in the line with the first
amplifier. Remove the DC block from the optional second amplifier.
Notes:
• The In-Line Signal 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.
• If you connect another amplifier in the line with the first amplifier, make sure there is at
least 100 feet between each In-Line Signal Amplifier.

PROBLEM SOLVING
If the satellite/TV/radio receiver does not operate correctly after you install the In-Line Signal 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 satellite/TV/ra-
dio receiver again. If possible, try a different satellite/TV/radio receiver with the system or try
the satellite/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.
