If an outside antenna is connected to the
product, be sure the antenna system is
grounded so as to provide some
protection against voltage surges and
built-up static charges. Section 810 of
the National Electric Code, ANSI/NFPA
70, provides information with respect to
proper grounding of the mast and
supporting structure, grounding of the
lead-in wire to an antenna discharge
product, size of grounding conductors,
location of antenna discharge product,
connection to grounding electrodes and
requirements for grounding electrodes.
