VU-75XR VHF/UHF/FM Antenna with Matching Transformer
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.
ASSEMBLING THE ANTENNA
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.
Note: To access the mast clamp holes, move the antenna’s
elements out of the way as needed.
2. Press the supplied large end plugs into the main boom.
CONNECTING LEAD-IN CABLE
TO THE 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.)
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.
Using Coaxial Cable
To connect coaxial cable to your antenna:
1. Thread the supplied matching transformer’s spade termi-
nals through the antenna’s strain-relief tab.
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.
3. Screw the cable’s F-connector onto the matching trans-
former.
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.
Using Twin-Lead Cable
To connect flat, twin-lead cable to your antenna:
1. Split one end of the twin-lead cable for a length of about 3
inches. Then strip about 1/2inch of insulation from both
leads.
2. Thread the stripped leads through the antenna’s strain-
relief tab.
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.

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
using the supplied 11/2-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 11/4-inch
screws and small wing nuts, as shown.
ATTACHING TO THE MAST
We recommend that you enlist the help of another person be-
fore 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 informa-
tion sheet for recommended methods.
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.
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 1/2inch of clearance
between parts.
3. Set up the mast, then rotate it so the antenna’s shorter ele-
ments point toward the broadcast antennas of the stations
you want to receive.
ROUTING THE CABLE TO YOUR
TV/VCR/FM RECEIVER
If you use coaxial cable:
• 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 coax-
ial cable enters the house. Read the Consumer Product
Safety Commission sheet for grounding instructions.
• Use a wall-through lead-in tube (not supplied) to neatly
route the coaxial cable through walls.
If you use twin-lead cable:
• Be sure the twin-lead cable remains at least 4 inches away
from all metal surfaces.
• Use standoff insulators about every 4 feet. Twist the twin-
lead cable about three turns between standoff insulators.
• Read the separate Consumer Product Safety Commission
sheet for grounding instructions.
