AMPLIFIED ANTENNAS

You can use the In-Line Signal Amplifier with amplified antenna systems, as shown in "Installa-
tion D."
If the power supply provided with your amplified antenna provides a center-positive power sup-
ply, it can be used to power the In-Line Signal Amplifier as well; you do not need the amplifier's
power injector.
The In-Line Signal Amplifier cannot be used if the amplified antenna power supply is
Caution:
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 amplifi-
er 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 proce-
dures 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 anten-
na systems (such as scanners, for example), you will have to use connection adapters or make
a special cable.
