Coaxial Cable Installation Precautions
•
Do not bend the coaxial cable into less than a three-inch radius. Tighter bends can cause shorts and
can change the cable’s impedance.
•
Do not install the coaxial cable where it will have a pulling tension greater than 15 pounds during
installation. After installation, make sure there is no tension on the cable.
•
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 the coaxial cable.
•
Do not expose the coaxial cable to a temperature greater than 176 degrees Fahrenheit. Keep the cable
away from heating vents and water heaters.
•
The cable jacket withstands most outdoor environments. However, you must seal the connections and
splices against water entry.
Connecting the Antenna to Your TV
To connect the antenna to your TV, follow these steps:
1. Connect the coax downlead from the antenna to the ANT jack on the power injector.
2. If your TV has an F-connector, connect the short coaxial cable on the power injector to your TV’s
VHF/UHF 75-ohm F-connector.
If your TV has screw terminals for the VHF/UHF connection, connect a 75-ohm to a 300-ohm
transformer (not supplied) between the power injector and the VHF/UHF terminals.
If your TV has a 75-ohm VHF connection and a 300-ohm UHF connection, connect a signal splitter
(not supplied) between the power injector and the TV’s VHF/UHF connections.
Lightning Protection for Exterior Mounting
•
Mount a grounding block (not supplied) as close as possible to the point where the downlead
enters the house.
•
The 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 four to six feet apart.
•
For a “ground-up” antenna installation, you may not need to ground the mast if it extends four
or more feet into the earth.
