ONE ANTENNA/ONE RECEIVER SYSTEMS

If you are using a single antenna with a single TV/radio receiver, “Installation A” shows the proper connections. 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 the connection labeling on the amplifier/DC block unit: TO ANTenna, TO POWER INJECTOR. 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.

•If a VHF/UHF splitter is used for a TV, it must be connected between the TV and the power injector.

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