Step 3: Unfold 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 using the supplied 1½-inch screw and small wing
nut, as shown.

5. Insert the top and bottom wing booms into the wing
boom brackets. Secure them with the four supplied 1¼-
inch screws and small wing nuts, as shown.

Step 4: Attach Antenna to the Mast
We recommend that you enlist the help of another person
before you put up the mast or attach your antenna to
it. How you set up your mast depends on your specific
installation. Refer to the separate Consumer Product
Safety Commission information sheet for recommended
methods.
1. Slide the antenna's mast clamp assemblies over the end
of the mast.
2. Tighten the mast clamp assemblies' lock nuts to hold
the antenna in place. Do not overtighten the lock nuts.
Caution: The crossover wires must not touch the antenna
boom, the mast, or each other. If necessary, carefully bend
the crossover wires to provide at least ½-inch of clearance
between parts.

3. Set up the mast, then rotate it so the antenna's shorter
elements point toward the broadcast antennas of the
stations you want to receive.

Step 5: Route Cable to Your Audio/Video System
• Use plastic tape or mast standoff insulators to secure
the coaxial cable to the mast at about 3-foot intervals.
Continue down the roof and the side of the house using
roof and wall standoff insulators.
• Use coaxial cable nail-in clips every few feet to secure
the cable between the mast and where the cable enters
the house.
• Use a 75-ohm grounding block at the point where the
coaxial cable enters the house. Read the Consumer
Product Safety Commission information sheet for
grounding instructions.
• Use a wall-through lead-in tube (not supplied) to neatly
route the coaxial cable through walls.
• Loosely bend the cable to form a drip loop before the
cable enters the house.
Step 6: Connect to your Audio/Video System
Connect the antenna's coaxial cable to your audio/video
system's antenna terminals according to the type of
connections you have. RadioShack carries a variety of
splitters and other accessories; choose one that best suits
your needs. Below are some sample connections.
If you have:
• Twin-lead UHF terminals
• Coaxial VHF terminal
• Twin-lead FM antenna terminals
Use a RadioShack Splitter with 75-Ohm Input

If you want to:
• Use the antenna in combination with a cable or satellite
set-top-box, and
• Your TV has a coaxial (antenna in) terminal.
Use a RadioShack High Isolation A/B Switch.
