3. 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-in terminals (one for each half of the UHF bowtie on each side of the boom). UHF/VHF Isolation Network UHF Bowtie Lead-In Terminal Note: Both sections of the UHF/VHF isolation network should remain parallel to the main 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, 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 cable before you attach the F-connector.

Thread the supplied matching transformer’s spade terminals through the antenna’s strain-relief tab. 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. © 1998, 2000 Tandy Corporation. All Rights Reserved.

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 strain- relief 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 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. 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.

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. Crossover Wires 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.

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 ca...
