OWNER’S MANUAL — Please read before using this equipment.  
3. Press the supplied large end plugs into the main boom and  
the cradle boom.  
BEFORE YOU BEGIN  
Before you begin installation, read this manual and the sepa-  
rate Consumer Product Safety Commission information sheet.  
For your safety and convenience, plan each step of the installa-  
tion and purchase the necessary hardware in advance. The  
hardware required and the order in which you perform the steps  
depend on the mounting and connection method you choose.  
CONNECTING LEAD-IN CABLE  
TO THE ANTENNA  
We recommend RG-6 cable and, if you prepare your own ca-  
ble, a quality F-connector. You can also use 300-ohm flat, twin-  
lead cable. (RadioShack carries a variety of suitable cables and  
connectors.)  
Warning: When you install your antenna, use extreme caution.  
If the antenna starts to fall, let it go! It could contact overhead  
power lines. If the antenna touches the power line, contact with  
the antenna, mast, cable, or guy wires can cause electrocution  
and death. Call the power company to remove the antenna. Do  
not attempt to remove it yourself.  
Note: If you prepare your own coaxial cable, be sure to slide  
the supplied matching transformer’s weather boot onto the ca-  
ble before you attach the F-connector.

If you plan to add this antenna to a VHF antenna’s mast, refer  
to “Adding the UHF Antenna to a VHF Antenna Installation” on  
Page 2 for instructions. This type of setup requires twin-lead  
cable. See “Using Twin-Lead Cable” on Page 2 to connect the  
cable to your antenna. If you are connecting this UHF antenna  
directly to your TV, follow these steps to make this connection  
using coaxial cable.

2. Attach the other mast clamp assembly to the cradle boom.  
(Be sure it faces the same direction as the main boom’s  
mast clamp assembly, shown above.) Fold out the two sets  
of metal support straps on the cradle boom and attach  
them to the corresponding holes on the main boom using  
the two supplied 11/2-inch screws and large wing nuts.  
1. Thread a matching transformer’s spade terminals through  
the antenna’s strain-relief tab. (Matching transformers are  
available at your local RadioShack store.)  
2. Slide the spade terminals around the antenna’s lead-in ter-  
minals (on both sides of the boom), then secure them with  
the supplied flat washers and large wing nuts.  
Cradle Boom  
3. Screw the cable’s F-connector onto the matching trans-  
former.  
4. Slip the weather boot over the connection. If you use a  
rebuilt cable without a weather boot, cover the connection  
with weather-resistant tape.

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.)  
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:  
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.  
• 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.  
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.)  
• Use coaxial cable nail-in clips every few feet to secure the  
cable between the mast and where the cable enters the  
house.  
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).  
• 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.  
Twin-Lead Cable  
to UHF Antenna  
• Use a wall-through lead-in tube (not supplied) to neatly  
route the coaxial cable through walls.  
VHF Antenna’s  
Lead-In Terminal  
If you use twin-lead cable:  
• Be sure the twin-lead cable remains at least 4 inches away  
from all metal surfaces.  
Flat Washers  
• Use standoff insulators about every 4 feet. Twist the twin-  
lead cable about three turns between standoff insulators.  
LargeWing  
Nuts  
• Read the separate Consumer Product Safety Commission  
sheet for grounding instructions.  
7. Replace the spade terminals (if removed in Step 5), flat  
washers, and large wing nuts.  
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
