3.Use only about 70 inches of twin-lead cable to connect your 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. Connect the cable to your UHF antenna first. (Follow the steps in the section “Using Twin-Lead Cable” on Page 2.)

4.Split the other end of the twin-lead cable for a length of about 3 inches. Then strip about 1/2 inch of insulation from both leads.

5.Remove the VHF antenna’s large wing nuts and flat wash- ers from its lead-in terminals. (If you used coaxial cable to connect the VHF antenna to your TV, also remove the spade terminals from the lead-in terminals.)

6.Wrap each lead of the twin-lead cable around one of the VHF antenna’s lead-in terminals (on both sides of the boom).

7.Replace the spade terminals (if removed in Step 5), flat washers, and large wing nuts.

Note: In some locations, you might need to use an indoor/out- door 300-ohm splitter/combiner (available at your local Ra- dioShack store) to receive a satisfactory picture on your TV.

ROUTING THE CABLE TO YOUR TV/VCR

If you use coaxial cable:

Use plastic tape or mast standoff insulators to secure the coaxial cable to the mast at about 3-foot intervals. 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 coax- ial 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.

CONNECTING TO YOUR TV/VCR

Connect the antenna’s lead-in cable to your TV/VCR’s antenna terminals according to the type of cable you used. RadioShack car- ries a variety of matching transformers, if one of these suits your needs. Below are some sample connections.

Make connections as described if you have:
