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.
