OUTDOOR ANTENNA GROUNDING
It an outside antenna Is connected to your tuner or lurIer-prearnplltler, 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 No. 70-1984, provides information with
respect to proper grounding of the mast and supponing structure, grounolng
ol the lead-in wire to an antenna discharge unit, size at grounding
conductors, location of antenna discharge unit, connection to grounding
electrodes, and requirements for the grounding electrode.
a. Use No.10 AWG (5.3 mm“) copper. No.8 AWG (6.4 mm‘) aluminum,
No.17 AWG (1,0 mm?) copper-clad steel or bronze wire, or larger, as a
o, secure antenna lead-In and ground wrres ro nouse wrtn stand-ctr
insulators spaced from 0-61eet (1 .22-1 .83 m) apart.
c. Mount antenna discharge unit as close as possible to where lead-in
d, Use jumper wire not smaller than No.6 AWG (13.3 mm”) copper. or the
equivalent, when a separate antenna-grounding electrode is used. See NEC
Section 310-21 (i).

NOTE TO CATV SYSTEM INSTALLER
This reminder is provided to call the CATV system installers attention to
Article 82022 of the National Electrical Code 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 to the point of
cable entry as practical.
