Using Coaxial Cable
BEFORE YOU BEGIN
Before you begin installation, read this manual and the sepa-
rate Consumer Product Safety Commission information sheet.
For your safety and convenience, plan each step of the installa-
tion and purchase the necessary hardware in advance. The
hardware required and the order in which you perform the steps
depend on the mounting and connection method you choose.

Warning: When you install your antenna, use extreme caution.
If the antenna starts to fall, let it go! It could contact overhead
power lines. If the antenna touches the power line, contact with
the antenna, mast, cable, or guy wires can cause electrocution
and death. Call the power company to remove the antenna. Do
not attempt to remove it yourself.

2. Slide the spade terminals around the antenna’s lead-in ter-
minals (on both sides of the boom), then secure them with
the supplied flat washers and large wing nuts.
Assemble the entire antenna on the ground.
1. Use the supplied hardware to loosely attach the supplied
mast clamp assembly to the main boom, as shown.
3. Screw the cable’s F-connector onto the matching trans-
former.

CONNECTING LEAD-IN CABLE
TO THE ANTENNA
To connect flat, twin-lead cable to your antenna:
We recommend RG-6 cable and, if you prepare your own ca-
ble, a quality F-connector. You can also use 300-ohm flat, twin-
lead cable. (RadioShack carries a variety of suitable cables and
connectors.)
1. Split one end of the twin-lead cable for a length of about 3
1
inches. Then strip about /2 inch of insulation from both
leads.
2. Thread the stripped leads through the antenna’s strain-
relief tab.
Note: If you prepare your own coaxial cable, be sure to slide
the supplied matching transformer’s weather boot onto the ca-
ble before you attach the F-connector.
3. Wrap each lead around one of the antenna’s lead-in termi-
nals (on both sides of the boom). Be sure there is enough
slack between the strain-relief tab and the antenna termi-
nals to prevent stress on the cable or the terminals.
4. Secure the leads with the supplied flat washers and large
wing nuts.
