INTRODUCTION
The RadioShack Satellite/TV/ FM In-Li ne Sign al Ampl ifier bri ngs to your home v ideo s ystem th e
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 transformers, signal splitters, other in-line devices or extremely long cable runs between the antenna 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 d es ign o f the am pl ifier simplifies instal lat ion at the “head end” of an a nte nna 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 connections.
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.
• Follow the connection labeling on the amplifier/DC block unit:
TO ANT, TO POWER INJEC-
TOR
. The amplifier will not receive power if they are reversed.
• Follow the con n ec ti o n l abe l in g o n t he po w e r in j ec t or:
TO TV, TO AMPLIFIER
. Your TV/radio
receiver will be damaged if they are reversed.
Note:
The In-Line Signal Amplifier is d esign ed for us e with F- typ e connec tors. For some a ntenna systems (such as scanners , for exa mple), you will have to use co nnecti on adapters or m ake
a special cable.

Installation A
Caution:
To avoid damage to the amplifier, power injector or other connected equipment, do
not plug in the power injector until all connections have been double-checked.
Note:
An antenna transformer might no t be in cluded with your antenna and mi ght not be need-
ed. Check your antenna’s owner’s manual.

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, caref ully check all the points listed below.
Note:
Make sure the power injector is between the amplifier and the splitter (before the signal
is split).

ONE SATELLITE DISH/RECEIVER SYSTEM
Your In-Line Signal Amplifier ca n be us ed i n a one -w ire s ol uti on th at a ll ows y ou to com bin e th e
direct-to-home signal from your s atell ite dis h and th e VHF/UHF signa l from y our TV an tenna b y
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/receiver 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 direct-to-home signal, then route them to the TV’s antenna input and the direct-to-home receiver’s input. See the connection in “Installation C.”

AMPLIFIED ANTENNAS
You can use the In-Line Signal Amplifier with amplif ied antenna systems, as s hown in “Installation D.”
If the power supply provi ded with yo ur amplified antenna provid es a c en ter-p osi tiv e p ow er su pply, it can be used to pow er the In-L ine Sig nal Amp li fier as well; you do not need th e am pl ifi er’ 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 amplifier 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 procedures 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 d esigned for use w ith F- type c onnectors . For som e ante nna systems (such as scanners , for exa mple), you will have to use co nnecti on adapters or m ake
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 secon d amplifie r in your sy stem, ret ain the ext ra parts fo r
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 foun d in t he co nnec tio ns:
Plug in the power injector and try the satel lit e/TV/radio 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.
