Outdoor Antenna Grounding If an outside antenna is
connected to the receiver, be sure the antenna system is
grounded so as to provide some protection against voltage
surges and built-up static charges. Section 810 of the Na-
tional Electrical Code, ANSI/NFPA No. 70-1984, 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, loca-
tion of antenna-discharge unit, connection to grounding
electrodes, and requirements for the grounding electrode.
See figure below.
Power Lines An outside antenna should be located away
from power lines.
