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 Electric Cord, ANSI/NFPA No. 70-1984, provides information with respect to
proper grounding of the mats and supporting structure grounding of the lead-in wire to an
antenna-discharge unit, size of grounding connectors, location of antenna-discharge unit, connection to
grounding electrodes and requirements for the grounding electrode. See Figure below.
EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL CODE
