15-1170.fm Page 4 Tuesday, July 13, 1999 4:35 PM 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.
15-1170.fm Page 5 Tuesday, July 13, 1999 4:35 PM 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.
15-1170.fm Page 6 Tuesday, July 13, 1999 4:35 PM 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.

Note: An antenna transformer might not be included with your antenna and might not be needed. Check your antenna’s owner’s manual.
15-1170.fm Page 8 Tuesday, July 13, 1999 4:35 PM 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 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 is split).
15-1170.fm Page 9 Tuesday, July 13, 1999 4:35 PM 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.
15-1170.fm Page 10 Tuesday, July 13, 1999 4:35 PM Note: Normally, the direct-to-home receiver supplies power to both the antenna amplifier and the LNB converter.
15-1170.fm Page 11 Tuesday, July 13, 1999 4:35 PM 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.

15-1170.fm Page 13 Tuesday, July 13, 1999 4:35 PM 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.
15-1170.fm Page 14 Tuesday, July 13, 1999 4:35 PM 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.
