INSTALLATION 

Cautions: 

• For outdoor antennas, install an

antenna grounding system, as
shown in the supplied sheet. 

• The power supply has a protection

circuit that shuts down the ampli-
fier if there are stray wires
between the power supply and the
amplifier. If the amplifier does not
operate, check for stray wires.
Proper operation should resume
when the problem is corrected. 

Installing the Amplifier

1. Mount the amplifier on the

antenna mast, about 12 inches
below the antenna. Position the U-
bolt and mounting bracket as
shown. Then install washers and
tighten the nuts securely. 

2. Attach one end of the provided

coaxial cable to the amplifier’s F-
connector labeled 

TO ANTENNA

.

Attach the other end of this cable
to the antenna’s terminals, using
the supplied 300-to-75 ohm
matching transformer if necessary. 

Notes: 

• Be sure to fully seat the weather

boots provided on the coaxial
cable over their corresponding
F-connectors. 

• Leave a slight amount of slack

(called a drip loop) where the
cable attaches to the amplifier. 

3. Choose a length of cable long

enough to reach from the antenna
to your TV or receiver. Ra-
dioShack stores have various pre-
cut lengths of cable with boots and
connectors in place. If you choose
to assemble your own coaxial
cable, use the supplied weather-
boot at the amplifier’s connections.
