Safety Instructions

14. Outdoor Antenna Grounding

If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so as to provide some pro- tection against voltage surges and built-up static charges. Article 810 of the National Electrical Code (U.S.A.), ANSI/ NFPA 70 provides informa- tion with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of ground- ing conductors, location of antenna-discharge unit, connection to ground- ing electrodes, and requirements for the grounding electrode.
