Outdoor Antenna GroundingBefore attempting

34、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 (5.3mm2) copper, No.8 AWG (8.4mm2) aluminum, No.17 AWG (1.0mm2) copper-clad steel or bronze wire or larger, as ground wire.

35、 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. A driven rod may be used as the grounding electrode where other types of electrode

36、 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 13.3mm2) copper or equivalent, when a separate antenna grounding electrode is used.
