VHF/UHF Amplified Antenna
(illus)
Your RadioShack VHF/UHF Amplified Antenna provides
excellent reception of VHF and UHF broadcast TV channels in most viewing locations. The antenna’s supplied
power injector helps you boost the signal through a long
coaxial cable for better recept ion. You can connect the antenna either directly to your TV or to your direct-to-home
satellite system. The antenna’s compact modern styling
blends well with the decor of almost any home, and you
can install it in a variety of places such as your attic, loft,
or garage. The antenna’s UV-protected housing is made
of impact-resistant filled copolymer, making the exterior
resistant to weathering and color change. The antenna’s
built-in fixed FM trap helps prevent strong FM stations
from interfering with TV Channels 2–13.
To avoid electric shoc k, please read and foll ow these i mportant safety precautions:
• Be sure to select an antenna site well away from all
overhead wires.
• Do not try to guess which overhea d wires carry high
voltage. Check with the power company.
• If you notice a nything making contact with th e overhead wires, call the power company to have it
removed safely.
• Do not run the antenna’s cable over power wires.
• Get help from a qualified professional wh en rem ov ing
the old antenna if there is an y doubt of clearing o verhead wires.
• Never install an antenna by yourself. Be sure to have
at least two people available for help, if needed.
• Never install the antenna when it is windy.

IMPORTANT SAFETY PRECAUTIONS
Many do-it -yoursel f and profe ss ional antenna install ers are
injured or killed each year by electric shock. Many power
wires ar e within 20 to 25 feet of the ground and could easi ly be touched by an assembled antenna or cable. Touching the overhead wires with any part of the antenna is the
same as touching the wires with your bare hand. Contacting an electrical wire almost always results in a very serious shock.
WARNING
use extreme caution. If the antenna starts to fall,
let it go! It could contact overhea d power l ines. If
the antenna touches the power line, contact with
the antenna, mast, cable, or guy wires can c ause
electrocution and death. Call the power company
to remove the antenna. Do not attempt to remove
it yourself!

Coaxial Cable Installation Precautions
(illus)
• Do not bend coaxial cable (RG-6/U) into less than a
3-inch radius. Tighter bends can cause shorts and
change the cable’s impedance.
• Do not install coaxial cable where it will have a pulling
tension of greater than 50 pounds. Leave no tension
on the cab le a f ter in s t alling it.
• Use only round-headed staples. Any clamps or
securing devices used with coaxial cabl e should grip
the cable evenly about the circumference without
crushing the cable. Flat staples c an damage coaxial
cable.
• Do not expose coaxial cable to a temperature greater
than 176°F (80° C). Keep the cable away from heating vents and water heaters.
• Do not install coaxial cable where it will be crushed,
stuffed, wedged, or pinched.
• The cable jacket withstands most outdoor environments. However, you must seal connections and
splices against water entry.
3. Thread one of the supplied screws through the antenna’s center mounting hole. Then use a Phillips
screwdriver to temporarily secure the antenna to the
mounting surface.
To make sure the mounting location y ou chose
Hint:
is the best place for reception of all channels, follow
the steps in “Connecting the Antenna” on Page 3
then tune each of your TV’s channels. If you can tune
all channels, continue with Step 4 to finish mount ing
the antenna. If you cannot tune one or m ore of the
channels, move the antenna to another location and
try again.
4. If necessary, use a carpenter’s level or other leveling
device (not supplied) to make sure the antenna is
horizontal. Then mark the positions for the left and
right screw holes on the mounting surface.
MOUNTING THE ANTENNA
You can mount y our antenna in doors or outdo ors on just
about any flat surface. For the best results, mount the antenna horizontally as hig h as poss ib le awa y from tr ees or
other obstructions. (Higher frequencies are noticeably affected by obst ruction s.) Mak e su re t he front o f the antenna faces the general dire ction of the nearest T V station’s
broa dcas ting ant enna.
Important:
face such a s aluminum siding. This greatly reduces the
antenna’s ability to receive signals.
Outdoor Mounting
1. Mark the position for the center m ounting screw h ole
on the mounting surface.
2. In the marked location, drill a hole slightly smaller
than one of the supplied 1
Caution:
behind the surface.
Do not mount the antenna on an y metal sur-

/4-inch screws.
Be careful not to drill into any objects
5. In each marked locati on, drill a hole slightly smalle r
than the screw.
6. Thread the remaining supplied screws through the
antenna’s left and right mounting holes, then use a
Phillips screwdriver to t ighten all screw s and attach
the antenna to the mounting surface.
Indoor Mounting
You can also mount the ant enna i n an atti c, cl oset , or other
out-of- t he way indoor location. T he antenna can be mounted on a horizontal mast, closet rod, or on a short piece of
mast suspended from a roof support by a 4-inch wallmount br ack et (such as Cat . No. 15-8 83, not supplied). Or,
you can simply place the anten na on a shelf in a closet. Be
sure the antenna is not in a position where it could easily
fall or be damaged.
