15. 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 National
Electrical Code, ANSI/NFPA 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 Figure.
