15-1117a.fm Page 3 Thursday, July 15, 1999 11:15 AM 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 the 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

15-1117a.fm Page 4 Thursday, July 15, 1999 11:15 AM Caution: Because the In-Line Amplifier uses the coaxial cable to carry the TV/radio signal from 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 connection instru

To avoid damage to your TV/radio receiver and/or the amplifier power in- jector, 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 (Cat. No. 15-1140) at the antenna. • Follow

Remove the DC block from the optional second amplifier. One power injector will supply enough power for both amplifiers. Note: The In-Line Coaxial 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 fu

Caution: The In-Line Amplifier cannot be used if the ATV power supply is center negative. In this case only, you should re
