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. See example below.

tact with them might be fatal. Installing an outdoor antenna
can be hazardous and should be left to a professional antenna
installer.
