OUTDOOR ANTENNA GROUNDING

Ii an outslde antenna Is connected to your tuner ur turier~preaiiiplitioi. be
sure the antenna system is grounded so as to provide some protection
against voltage surges and built-up static charges. Section 810 oi the
National Electrical Code. ANSI/NFPA No. 70-1984, provides information with
respect to proper grounding or the mast and supponlng structure, grounding
oi 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.

a. Use No.10 AWG (5.3 mm-�) copper, No.8 AWG (8.4 mm-�) aluminum.
No.17 AWG (1.0 mm-�) copper-clad steel or bronze wire. or larger. as a
ground wire.

D. secure antenna lead-In and ground wires to house with stand-on
Insulators spaced from 4-6 last (1,224.53 rn) apart.

c. Mount antenna discharge unit as close as possible to where lead«in
enters house.

(1. 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 810-21 (1).

NOTE TO CATV SYSTEM INSTALLER

This reminder is provided to call the CATV system installers attention to
Article 820-22 of the National Electrical Code that provides guidelines for
proper grounding and. in particular, specifies that the cable ground shall Lie
connected to the grounding system of the building, as close to the point of
cable entry as practical
