ments point toward the broadcast antennas of the stations
you want to receive.

ROUTING THE CABLE TO YOUR
TV/VCR/FM RECEIVER

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 AND FM RECEIVER

Connect the antenna’s lead-in cable to your TV/VCR and FM receiver’s antenna terminals according to the type of cable you used.
RadioShack carries a variety of splitters. Choose one that best suits your needs. Below are some sample connections.

Make connections as shown if you have:

• Coaxial antenna lead-in

• Twin-lead UHF terminals

• Coaxial VHF terminal

• Twin-lead FM antenna terminals

Make connections as shown if you have:

• Coaxial antenna lead-in

• Twin-lead UHF terminals

• Twin-lead VHF terminals

• Twin-lead FM antenna terminals
