21. Outdoor Antenna Grounding—Before attempting to install this prod-
uct, be sure the antenna or cable system is grounded so as to provide some
protection against voltage surges and built-up static charges.
a. Use No.10 AWG (5.3mm?) copper, No.8 AWG (8.4mm?) aluminum,
No.17 AWG (1.0mm?) copper-clad steel or bronze wire or larger, as ground
wire.
b. Secure antenna lead-in and ground wires to house with stand-off
insulators spaced from 4 feet (1.22m) to 6 feet (1.83m) apart.
c. Mount antenna discharge unit as close as possible to where lead-in
enters house.
d. Adriven rod may be used as the grounding electrode where other types
of electrode systems do not exist. Refer to the National Electrical Code,
ANSI/NFPA 70-1990for information.
e, Use jumper wire not smaller than No.6 AWG 13.3mm?) copper or
equivalent, when a separate antenna grounding electrode is used.
