Any outdoor antenna must be located away from all power lines.
OUTDOOR ANTENNA GROUNDING
ii an outside antenna is connected to your tuner or tuner—preamplifier. 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. 70-1584. provides information with
respect to proper grounding oi the mast and supporting structure, grounding
ot the lead-in wire to an antenna discharge unit. size at grounding
conductors, location of antenna discharge unit, connection to grounding
electrodes. and requirements tor the grounding electrode.
3. Use No.10 AWG (5.3 mm‘i copper, No.8 AWG (8.4 mm’) aluminum,
No.17 AWG (1.0 mm‘) copper~clad steel or bronze wire. or larger, as a
b. Secure antenna lead-in and ground wires to house with stand-cit
insulators spaced from 4—6 feet (1.22-1.83 mi apart.
c. Mount antenna discharge unit as close as possible to where toad-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 810—21 (i).
