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. 11/2-Inch BracketsWing Boom Main Boom Screw Small Wing Nut 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. Top Wing Boom Small Wing Nuts Bottom Wing Boom Wing Boom Brackets 11/4-Inch Screws 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 the 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.

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.”) 2 15-2162a.fm Page 3 Thursday, April 27, 2000 2:21 PM 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).

CONNECTING TO YOUR TV/VCR Note: In some locations, you might need to use an indoor/outdoor 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. 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 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. Connect the antenna’s lead-in cable to your TV/VCR’s antenna terminals according to the type of cable you used. RadioShack carries a variety of matching transformers, if one of these suits your needs. Below are some sample connections.
