Outdoor Antenna Grounding: If an outside
antenna or cable system is connected to
the video product, be sure the antenna or
cable system is grounded so as to provide
some protection against voltage surges and
built-up static charges. Section 810 of the
National Electrical Code, ANSI/NFPA No. 70,
provides information with respect 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.
