Lightning Protection (when mounting the antenna
outside):
• Ground wires for both the mast and downlead should
be copper or aluminum wire, 8 AWG or larger.
• Mount a grounding block, such as Radio Shack Cat.
No. 15-909, as close as possible to where the down-
lead 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.
• For a “ground up” antenna installation, you might not
need to ground the mast if the mast extends 4 or
more feet into the earth.
Inside Mounting
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 (such as Cat. No. 15-883, not sup-
plied).
Or, you can simply place the antenna on a shelf in a clos-
et. Be sure the antenna is not in a position where it could
easily fall or be damaged.
CONNECTING THE ANTENNA TO
YOUR TV
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
piece of coax cable from the power injector to your
TV’s VHF/UHF 75-ohm F-connector.
If your TV has screw terminals for VHF/UHF connec-
tion, connect a 75-to-300 ohm transformer (such as
Cat. No. 15-1140, 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 (such
as Cat. No. 15-1231, not supplied) between the
power injector and the TV’s VHF/UHF connections.
