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:
• Coaxial antenna lead-in
• Twin-lead TV/VCR antenna terminals
