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
