19. Outdoor Antenna Grounding
– If an outside antenna or cable system is
connected to the product, be sure the antenna
or cable system is grounded so as to provide

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.
