Your Radio Shack Amplified Omnidirectional

VHF/UHFTV Antenna provides excellent reception of VHF/UHF TV channels in most viewing locations. The UV-protected housing is made of impact-resistant filled co-polymer, making the exterior resistant to weathering and color change. The antenna’s unique omnidirectional characteristics provide excellent reception in areas where broadcasts are received from different directions.

The built-in fixed FM trap helps prevent strong FM stations from interfering with TV

Channels 2–13.

Use extreme caution when installing an outdoor antenna close to overhead wires. If the antenna starts to fall, let it go! If any part of the antenna makes contact with overhead power lines, touching 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!

+/2146#06"5#('6;"24'%#76+105

Many do-it-yourself and professional antenna installers are injured or killed each year by electric shock, because they fail to recognize overhead wires as being potentially lethal.

Touching any part of the antenna mast or guy wire to these overhead wires is the same as touching the wires with your bare hand.

• If you notice anything making contact with the overhead wires, call the power company to have it removed safely.

• Do not run the downlead cable over power wires.

• Get help from a qualified professional when removing the old antenna if there is any doubt of clearing overhead wires.

A very serious shock is almost sure to result when contacting an electrical wire. In the case of primary wires on the top of poles, the shock is like being struck by a bolt of lightning. Many power wires are within 20 to

25 feet of the ground and could easily be touched by an assembled antenna and mast.

Please read and follow these important safety precautions:

• Never install an antenna when it is windy.

• Be sure to do all assembly work on the ground, then raise the antenna.

• Make sure the antenna mast downlead cable is connected to suitable lightning arrestors.

• Be sure to select an antenna site well away from all overhead wires.

• Use 8 (or larger) AWG ground wire between the mast and ground.

• Do not try to guess which overhead wires carry high voltage. Check with the power company.

• Make sure the installation is secure. Use plenty of guy wires and new hardware.

This antenna system is designed to work properly when the power injector is connected to the antenna through a 75-ohm coax cable.

• there are no shorts in the connection between the power injector and antenna

The coax cable between the power injector and the antenna carries:

The power injector’s indicator lights to show that:

• DC power from the power injector to the amplifier board in the antenna

• DC power is supplied to the antenna

If installing the antenna in a motor home, we recommend you use a 12V DC cord (not supplied, available at your local RadioShack store and online at RadioShack.com).

• the amplified TV signal from the antenna, through the power injector, to the video equipment

If any devices (such as amplifiers, splitters, combiners, matching transformers, 300-ohm cable) are used in your home cabling system, they must be connected between the power injector and your video equipment. Any devices connected between the power injector and the antenna might cause a short in the amplifier power source. If this happens, the injector’s indicator does not light and the signals to your video equipment (multiple TVs or VCRs) might be significantly degraded.

Before installing your antenna, perform this test to make sure it works properly.

1. Connect a temporary 75-ohm cable between the power injector’s ANT 75ohm jack and the antenna’s Fconnector.

±

2. Connect the power injector’s TV cable to your TV’s VHF/UHF 75-ohm Fconnector.

3. Insert the supplied AC adapter’s small plug into the DC 12V jack on the power injector.

±

4. Plug the supplied AC adapter into a standard AC outlet. If the power injector’s indicator lights, the antenna is properly connected.

You can mount the antenna in an attic, closet or other out-of-the way indoor location. The 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 wall-mount bracket (not supplied, available at

RadioShack).

Or, you can simply place the antenna on a shelf in a closet. Be sure the antenna is not in a position where it could easily fall or be damaged.

• Ground wires for both the mast and downlead should be copper or aluminum wire, 8 AWG or larger.

• Mount a grounding block (not supplied, available at RadioShack) as close as possible to where the downlead enters the house.

• Downlead wire from the antenna to the grounding block and the mast ground wire should be secured to the house with stand-off insulators, spaced 4–6 feet apart.

• 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 greater than 50 pounds maximum. Leave no tension on the cable after installing it.

• Use only round-headed staples. Any clamps or securing devices used with coax should grip the cable evenly about the circumference without crushing the cable. Flat staples can damage coax cable.

• Do not expose coaxial cable to a temperature greater than 176F (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.
