VU-190XR VHF/UHF/FM Antenna with Matching Transformer  
OWNER’S MANUAL — Please read before using this equipment.  
Your RadioShack VHF/UHF/FM Antenna performs better than  
standard antennas because of its special design features.  
2. Use the supplied hardware to loosely attach one of the sup-  
plied mast clamp assemblies to the main boom, as shown.  
U-Bolt  
UHF Bowtie — delivers more of the UHF signal to your TV.  
Since UHF signals are more difficult to receive than VHF sig-  
nals, this antenna gives UHF signals the extra boost they need.  
Mast Clamp  
VHF/UHF Isolation Network — prevents the two types of TV  
signals from interfering with each other. This results in cleaner  
signals and a better picture on your TV.

3. 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.  
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.  
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.

Assemble the entire antenna on the ground.  
4. Press the supplied large end plugs into the main boom and  
the cradle boom.  
1. Use the supplied hardware to assemble the two main boom  
sections, as shown. If necessary, lift one end of the main  
boom so the crossover wires reach the threaded posts.  
5. Pull the UHF bowtie’s two halves away from the main boom  
until they lock into place. Then slide each half’s unattached  
end over one of the antenna’s lead-in terminals (one for  
each half of the UHF bowtie on each side of the boom).  
Note: To access slots or holes during assembly, move the  
antenna’s elements out of the way as needed.

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.)

between parts.  
ROUTING THE CABLE TO YOUR  
TV/VCR/FM RECEIVER  
If you use coaxial cable:  
Crossover Wires  
• 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.  
3. Set up the mast, then rotate it so the antenna’s shorter ele-  
ments point toward the broadcast antennas of the stations  
you want to receive.  
• 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.  
Toward TV  
Stations’  
Antennas  
• 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.
