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, size of grounding conductors, location of antenna-discharge unit,
connection to grounding electrodes, and requirements for the grounding electrode.
