lOutdoor 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. See
Figure.
