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.
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 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.
