Before You Begin
Before beginning installation, read this manual and
the separate
Consumer Product Safety Commission
Information Sheet
. For your safety and convenience,
plan each step of the installation 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.
Assembling the Antenna
Backup Plate
Lock Nuts
Main Boom
Mast Clamp
U-Bolt
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. Move the antenna’s elements out of the way
as needed to access the mast clamp holes.
2. Press the supplied large end plugs into the main
boom.
Connecting Coaxial Cable to the Antenna
We recommend RG-6 cable and, if you prepare your
own cable, a quality F-connector. (
RadioShack
carries a
variety of suitable cables and connectors.)
Note:
If you prepare your own coaxial cable, be sure to
slide the supplied matching transformer’s weather boot
onto the cable before you attach the F-connector.

Flat Washers
1. Thread the supplied matching transformer’s spade

2. Slide the spade terminals around the antenna’s
lead-in terminals (on both sides of the boom), then
secure them with the supplied flat washers and large
wing nuts.
3. Screw the cable’s F-connector onto the matching
transformer.
4. Slip the weather boot over the connection. If you
use a rebuilt cable without a weather boot, cover the
connection with weather-resistant tape.
Unfolding the Antenna’s Elements
1. Hold the main boom’s elements near the pivot
points and pull them away from the boom until they
snap into the self-locking plastic support insulators.
Caution:
To avoid damage to the elements, do not
pull them near their outer ends. Once the elements are
locked into position, do not attempt to unlock them.
Doing so might break the self-locking tabs.
2. Hold each wing boom and turn its elements until
they snap squarely into place (perpendicular to the
boom).
3. Press the supplied small end plugs into the wing
booms.
4. Bolt the triangular wing boom brackets onto the
main boom u sing the supplied 1½-inch screw and
small wing nut, as shown.

person before you put up the mast or attach your
antenna to it. Refer to the separate
Consumer
Product Safety Commission Information Sheet
for
recommended methods to set up your mast.
1. Slide the antenna’s mast clamp assembly over the
end of the mast.
2. Tighten the mast clamp assembly’s lock nuts to hold
the antenna in place. Do not overtighten the lock
nuts.
