Outdoor Antenna Grounding: If an outside antenna is con-
nected to the receiver, be sure the antenna system is ground-
ed, so as to provide some protection against voltage surges
and built up static charges. Section 810 of the National
Electrical Code, ANSI/NFPS No. 70-1983, 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-dis-
charge unit, connection to grounding electrodes, and require-
ments for the grounding electrode. See illustration below.
