Anleitung Zusammenfassung
Your RadioShack VHF/UHF/FM Antenna performs better than standard antennas because of its special design features. UHF Bowtie — delivers more of the UHF signal to your TV. Since UHF signals are more difficult to receive than VHF signals, this antenna gives UHF signals the extra boost they need. VHF/UHF Isolation Network — prevents the two types of TV signals from interfering with each other. This results in cleaner signals and a better picture on your TV. 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 assemble the two main boom sections, as shown. If necessary, lift one end of the main boom so the crossover wires reach the threaded posts. Note: To access slots or holes during assembly, move the antenna’s elements out of the way as needed.

Use the supplied hardware to loosely attach one of the supplied mast clamp assemblies to the main boom, as shown. Mast ClampU-Bolt Main Boom Backup Plate Lock Nuts 3. 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 11/2-inch screws and large wing nuts.

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).

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.

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. Using Twin-Lead Cable Main Boom Lead-In Terminal Twin-Lead Cable Lead-In Terminal Flat Washers Strain-Relief Tab 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. 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...
