connected to this unit, be sure the antenna 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.
