U-120XR UHF Antenna
OWNER’S MANUAL — Please read before using this equipment.
BEFORE YOU BEGIN
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 one of the sup­plied mast clamp assemblies to the main boom, as shown.
Note: To access the mast clamp holes, move the antenna’s elements out of the way as needed.

3. Press the supplied large end plugs into the main boom and the cradle boom.
CONNECTING LEAD-IN CABLE TO THE ANTENNA
We recommend RG-6 cable and, if you prepare your own ca­ble, a quality F-connector. You can also use 300-ohm flat, twin­lead cable. (RadioShack carries a variety of suitable cables and connectors.)
Note: If you prepare your own coaxia l cable, be sure to slide the supplied matching transformer’s weather boot onto the ca­ble before you attach the F-connector.

2. 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 1

If you plan to add this antenna to a VHF antenna’s mast, refer to “Adding the UHF Antenna to a VHF Antenna Installation” on Page 2 for instructions. This type of setup requires twin-lead cable. See “Using Twin-Lead Cable” on Page 2 to connect the cable to your antenna. If you are connecting this UHF antenna directly to your TV, follow these steps to make this connection using coaxial cable.
1. Thread a matching transformer’s spade terminals through the antenna’s strain-relief tab. (Matching transformers are available at your local RadioShack store.)
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.

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
/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-in termi­nals (on both sides of the boom). Be sure there is enough slack between the strain-relief tab 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 longer elements near the pivot poin ts and pull them away from the boom until they snap into the self-locking plastic support insulators.
Caution:
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.
To avoid damage to the elements, do not pull
5. Insert the top and bottom wing booms into the wing boom brackets. Secure them with the four supplied 1

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. If you plan to add this antenna to a VHF antenna’s mast, refer to “Adding th e UHF An­tenna to a VHF Antenna Installation” for instructions.
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.
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.

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 1

ADDING THE UHF ANTENNA TO A VHF ANTENNA INSTALLATION
To connect your UHF antenna to a VHF antenna, follow these steps.
1. Loosen the lock nuts on the VHF antenna’s mast clamp assembly. Slide the VHF antenna down the mast about 70 inches, then tighten the lock nuts to hold the antenna in place. Do not overtighten the lock nuts.
2. Mount your UHF antenna at the top of the mast. (See “Attaching to the Mast.”)

3. Use only about 70 inches of twin-lead cable to connect your UHF antenna to the VHF antenna. Be sure the cable is long enough to reach from the lead-in terminals of one antenna to the lead-in terminals of the other. Connect the cable to your UHF antenna first. (Follow the steps in the section “Using Twin-Lead Cable” on Page 2.)
4. Split the other end of the twin-lead cable for a length of about 3 inches. Then strip about
1
/2 inch of insulation from
both leads.
5. Remove the VHF antenna’s large wing nuts and flat wash­ers from its lead-in terminals. (If you used coaxial cable to connect the VHF antenna to your TV, also remove the spade terminals from the lead-in terminals.)
6. Wrap each lead of the twin-lead cable around one of the VHF antenna’s lead-in terminals (on both sides of the boom).

Note: In some locations, you might need to use an indoor/out-
door 300-ohm splitter/combiner (available at your local Ra­dioShack store) to receive a satisfactory picture on your TV.
ROUTING THE CABLE TO YOUR TV/VCR
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. Co ntinue 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 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 twin­lead cable about three turns between standoff insulators.
• Read the separate Consumer Product Safety Commission
