VU-190XRVHF/UHF/FM Antenna with Matching Transformer

OWNER’S MANUAL — Please read before using this equipment.

Your RadioShack VHF/UHF/FM Antenna performs better than standard antennas because of its special design features.

UHF Bowtie — delivers more of the UHF signal to your TV. Since UHF signals are more difficult to receive than VHF signals, this antenna gives UHF signals the extra boost they need.

VHF/UHF Isolation Network — prevents the two types of TV signals from interfering with each other. This results in cleaner signals and a better picture on your TV.

BEFORE YOU BEGIN

2.Use the supplied hardware to loosely attach one of the supplied mast clamp assemblies to the main boom, as shown.

Before you begin 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.

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 assemble the two main boom sections, as shown. If necessary, lift one end of the main boom so the crossover wires reach the threaded posts.

Note: To access slots or holes during assembly, move the antenna’s elements out of the way as needed.

3.Attach the other mast clamp assembly to the cradle boom. (Be sure it faces the same direction as the main boom’s mast clamp assembly, shown above.) Fold out the two sets of metal support straps on the cradle boom and attach them to the corresponding holes on the main boom using the two supplied 11/2-inchscrews and large wing nuts.

4.Press the supplied large end plugs into the main boom and the cradle boom.

5.Pull the UHF bowtie’s two halves away from the main boom until they lock into place. Then slide each half’s unattached end over one of the antenna’s lead-interminals (one for each half of the UHF bowtie on each side of the boom).

CONNECTING LEAD-INCABLE

TO THE ANTENNA

We recommend RG-6cable and, if you prepare your own cable, a qualityF-connector.You can also use300-ohmflat, twinlead 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 cable before you attach theF-connector.

To connect coaxial cable to your antenna:

1.Thread the supplied matching transformer’s spade terminals through the antenna’s strain-relieftab.

2.Slide the spade terminals around the antenna’s lead-interminals (on both sides of the boom), then secure them with the supplied flat washers and large wing nuts.

3.Screw the cable’s F-connectoronto 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-resistanttape.

To connect flat, twin-leadcable to your antenna:

1.Split one end of the twin-leadcable for a length of about 3 inches. Then strip about1/2 inch of insulation from both leads.

2.Thread the stripped leads through the antenna’s strainrelief tab.

3.Wrap each lead around one of the antenna’s lead-interminals (on both sides of the boom). Be sure there is enough slack between thestrain-relieftab and the antenna terminals 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 selflocking 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 theself-lockingtabs.

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-inchscrew and small wing nut, as shown.

ATTACHING 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 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 1/2 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.

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-footintervals. Continue down the roof and the side of the house using roof and wall standoff insulators.

Use coaxial cable nail-inclips every few feet to secure the cable between the mast and where the cable enters the house.

Use a 75-ohmgrounding block at the point where the coaxial cable enters the house. Read the Consumer Product Safety Commission sheet for grounding instructions.

Use a wall-throughlead-intube (not supplied) to neatly route the coaxial cable through walls.

If you use twin-leadcable:

Be sure the twin-leadcable remains at least 4 inches away from all metal surfaces.

Use standoff insulators about every 4 feet. Twist the twinlead cable about three turns between standoff insulators.

Read the separate Consumer Product Safety Commission sheet for grounding instructions.
