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 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 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 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 connection labeling on the power injector: TO TV , TO AMPLIFIER . Your TV/radio receiver will be damaged if they are reversed.

Note: The In-Line Signal Amplifier is designed for use with F-type connectors. For some antenna systems (such as scanners, for example), you will have to use connection adapters or make a special cable.

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/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 amplified antenna systems, as shown in “Installation D.”

If the power supply provided with your amplified antenna provides a center-positive power supply, 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 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 designed for use with F-type connectors. For some antenna 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/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.
