TV Antenna Connectors Protection External Television Antenna Grounding If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is electrically 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 electrical grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna-discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. Lightning Protection For added protection of any product during a lightning storm, or when it is left unattended and unused for long periods of time, unplug the product from the wall outlet and disconnect the antenna or cable system.

TV Antenna Connectors Protection
External Television Antenna Grounding
If an outside antenna or cable system is connected to the product, be sure the antenna or cable system
is electrically 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 electrical grounding of the mast and supporting structure, grounding of the lead-in wire to an
antenna-discharge unit, size of grounding conductors, location of antenna-discharge unit, connection
to grounding electrodes, and requirements for the grounding electrode.
Lightning Protection
For added protection of any product during a lightning storm, or when it is left unattended and unused
for long periods of time, unplug the product from the wall outlet and disconnect the antenna or cable
system. This will prevent damage to the product from lightning and power line surges.
