OUTDOOR ANTENNA GROUNDING

ii an outside amonna is mnnamad to your inner or tuner-preamplifier. be
sure the antenna system is grounded so as to provtde some protection
against voltage surges and built-up static charges, Section 510 at the
National Electrical Code. ANSI/NFPA No. 70-1964, proVides Information with
respect to proper grounding oi the mast and supporting structure. groundlna
ot 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

b. Secure antenna load-in and around wires to house with standoff
insulators spaced from 4-6 feet (1 22-1 .83 m) apart.

0 Mount antenna discharge unit as close as possmle 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
Section 310-21 (j).
