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.

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.
