Outdoor Antenna Grounding – If an outside antenna is
connected to the receiver, 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.
