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, any contact with the antenna, mast, cable, or guy wires can cause electrocution and death. Call the power company to remove the antenna.

Continue down the roof and the side of the house using roof and wall standoff insulators. • 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. Loosely bend the cable to form a drip loop before the cable enters the house. Step 6: Connect to your Audio/Video System Connect the antenna’s coaxial cable to your audio/video system’s antenna terminals according to the type of connections you have. RadioShack carries a variety of splitters and other accessories; choose one that best suits your needs. Below are some sample connections.

This section describes one method, which is to mount your HDTV/UHF antenna below the VHF and connect the two antennas with twin-lead cable. Visit your local RadioShack store to find the best method and mounting accessories for your installation. Note: You could also place your HDTV/UHF antenna above the VHF, but the coaxial cable must feed from the HDTV/ UHF antenna. Complete Step 1 through Step 3 on page 1 before beginning. 1. Remove the VHF antenna from the mast. 2. Mount your HDTV/UHF antenna about 48 inches (1.2 meters) from the top of the mast. (See Step 4: Attach Antenna to the Mast on page 1.) 3. Attach the VHF antenna to the mast. 4. Use about 5 feet (1.5 meters) of twin-lead cable to connect your HDTV/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. 5. Split both ends of the twin-lead cable for a length of about 3 inches (7.6 centimeters). Then strip about . inch (1.2 centimeters) of insulation from all leads. 6. Remove the hardware from the VHF antenna’s lead-in terminals. 7. Wrap each lead around one of the antenna’s lead-in terminals (on both sides of the boom) and secure with Optional Accessories RadioShack carries these and many other antenna mounting accessories: Outdoor Coaxial Cable Matching Transformer A/V Cable Tripod Mount Antenna Mast Antenna Rotator Grounding Block the hardware. Be sure there is enough slack between the strain-relief tab and the antenna terminals to prevent stress on the cable or the terminals.
