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.
