CONNECTING TO YOUR TV/VCR

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.

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.
