Ground outdoor antennas. If an outside antenna or cable system is connected to the Monitor, 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.70-1984, provides information
about 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.
