OUTDOOR ANTENNA GROUNDING

It an outside antenna is connected to your tuner or tuner-preamplifier, he
sure the antenna system is grounded so as to provide some protection
against voltage surges and built-up static charges. Section 810 at the
National Electrical Code. ANSI/NFPA No. 701984, provides intormation with
respect to proper grounding of the mast and supporting stmnture, grounding
oi the lead-in wire to an antenna discharge unit. size 01 grounding
conductors. location at antenna discharge unit. connection to grounding
electrodes, and requirements lor the grounding electrode.

a. Use No.10 AWG (5.3 mnr-) copper. No.8 AWG (8.4 mm-) aluminum.
No.t7 AWG (1.0 mm-) copper-clad steel or bronle wire. or larger. as a
ground wire.

b. Secure antenna lead-in and around wims in house with panic"
insulators spaced trom 4-6Ieet(1.22~1.83 m) apart.

c. 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 antennagrounding electrode is used. See NEC
Section 310-21 (j).
