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 ground-
ing 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, connec-
tion to grounding electrodes, and require-
ments for the grounding electrode.

be taken to keep from touching such power
lines or circuits as contact with them might
be fatal.
