20. 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 antennadischarge unit, size of grounding connectors, location of antennadischarge unit, connection to grounding electrodes and requirements for
the grounding electrode. See Figure below.
EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL
CODE
Note to the CATV system installer: This reminder is provided to call the CATV
system installer’s attention to Article 820-40 of the NEC that provides
guidelines for proper grounding and, in particular, specifies that the cable
ground shall be connected to the grounding system of the building, as close
