• Get help from a qualified professional when removing
the old antenna if there is any doubt of clearing over-
head 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.
• Be sure to do all assembly work on the ground, then
raise the antenna.
• Make sure the antenna mast downlead cable is con-
nected to suitable lightning arrestors.
• Use 8 (or larger) AWG ground wire between the mast
and ground.
• Make sure the installation is secure. Use plenty of
guy wires and new hardware.
IMPORTANT ANTENNA NOTES
This antenna system is designed to work properly when
the power injector is connected to the antenna through
only 75-ohm coax cable.
The power injector has an indicator light to indicate that:
• DC power is supplied to the antenna
• There are no shorts in the connection between the
power injector and antenna
The coax cable between the power injector and the an-
tenna is used for:
• Carrying DC power from the power injector to the
amplifier board in the antenna
• Carrying the amplified TV signal from the antenna,
through the power injector, to the video equipment
If any devices are used in your home cabling system
(such as amplifiers, splitters, combiners, matching trans-
formers, or 300-ohm cable), they must be connected only
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.
Pre-Installation Test
To make sure your antenna system works properly, per-
form this test before installing it.
1. Connect a temporary 75-ohm cable between the
power injector’s
ANT
75-ohm jack and the antenna’s
F-connector.
Note: If installing new lead-in cable, use the actual
cable to be used in the installation.
2. Connect the power injector’s TV cable to your TV’s
VHF/UHF 75-ohm F-connector.
3. Insert the supplied AC adapter’s small plug into the
DC 12V
jack on the power injector.
Note: If installing the antenna in a motor home, we
recommend you use a DC cord (such as Cat. No.
273-1533, not supplied).
4. Plug the supplied AC adapter into a standard AC out-
let. If the power injector’s indicator lights, the antenna
is properly connected.
