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. A driven 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.
