Antenna Installation Instructions
1. Outdoor Antenna Grounding
If an outside antenna or cable system is connected to the product be sure the antenna
or cable system is grounded so as to provide some protection against voltage surges
and built-up static charges, Article 810
of the National Electrical Code, ANSI/NFPA 70,
provides information with regard to proper grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna discharge unit, connection to grounding
electrodes, and requirements for the grounding electrode.
2. Lightning
For added protection for this product during a lightning storm, or when it is left
unattended and unused for long periods of time, unplug it from the wall outlet and
disconnect the antenna or cable system. This will prevent damage to the product due to
lightning and power-line surges. Do not disconnect the antenna or the power cord during
a heavy storm lighting may strike while you are holding the cable cord, causing serious
injury; turn off your LCD TV and wait for the weather to improve.
3. Power Lines
An outside antenna system should not be located in the vicinity of overhead power lines or
other electric light
or power circuits, or where it can fall into such power lines or circuits,
When installing an outside antenna system, extreme care should be taken to keep from
touching such power lines or circuits as contact with them might be fatal.
