manual abstract
BEFORE YOU BEGIN 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 toremove it yourself. ASSEMBLING THE ANTENNA Assemble the entire antenna on the ground. 1. Use the supplied hardware to loosely attach the supplied mast clamp assembly to the main boom, as shown. Note: To access the mast clamp holes, move the antenna’s elements out of the way as needed. Mast ClampU-Bolt Main Boom Backup Plate Lock Nuts 2. Press the supplied large end plugs into 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.

This type of setup requires twin-lead cable. See “Using Twin-Lead Cable” 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. Using Twin-Lead Cable Twin-Lead Cable Lead-In Terminals Flat Washers Strain-Relief Tab Main Boom 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. © 1997, 2000 Tandy Corporation. All Rights Reserved.

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 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.

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. 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 overtig...
