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. Using Twin-Lead Cable Main Lead-In Terminal Twin-Lead CableStrain-Relief Tab Boom Flat Washers Large Wing Nuts 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 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. © 1998, 2000 Tandy Corporation. All Rights Reserved. RadioShack is a registered trademark used by Tandy Corporation.

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. 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. 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 ele- ments 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 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. 2 15-2151.fm Page 3 Wednesday, April 26, 2000 8:25 PM CONNECTING TO YOUR TV/VCR AND FM RECEIVER Connect the antenna’s lead-in cable to your TV/VCR and FM receiver’s antenna terminals according to the type of cable you used.
