12 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-upstatic charges. Section 810 of the National Electrical Code, ANSI/NFPA No. 70-1984 (Section 54 of Canadian Electrical Code, Part 1) provides information with respect 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 example below.
