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
(Section 54 of Canadian Electrical Code, Part 1)
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. See example below.
