Outdoor Antenna Grounding
If an outside antenna or cable system is connected
to the product, be sure the antenna or cable system
is grounded so as to provide some protection against
voltage surges and built-up static charge.
Article 810 of the National Electrical Code, ANSI/
NFPA 70, provides information with reguards
to proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an
antenna discharge unit, and size of ground conduc-
tors, location of antenna-discharge unit, connection
to ground electrodes and requirements for the
grounding electrode.
Example of antenna grounding as per
National Electrical Code,
ANSI/NFPA 70
