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, loca-
tion of antenna discharge unit, connec-
tion to grounding electrodes, and re-
quirements for the grounding electrode.
