OUTDOOR ANTENNA GROUNDING

It on outside antenna is connected to your tuner or tuner preamplifier, be
sure the antenna system Is grounded so as to prowde some protection
against voltage surges and built-up static charges. Section 610 of the
National Electrical Code, ANSI/NFPA No. 70-1984, provides intormation with
respectto proper grounding oi the mast and supponing structure. grounding
of the lead-in wire to an antenna discharge unit. size 01 grounding
conductors, location of antenna discharge unit. connection to grounding
electrodes. and requirements lor 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.

b Secure antenna leadrln and ground wire: to house with standro"
insulators spaced trom 4-6 test (1 22-133 m) apart.

0. Mount antenna discharge unit as close as possible to where lead-in
enters house.

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
