Safety Instructions

9. Outdoor Antenna Grounding

If an outside antenna or cable system is connected to the TV be sure the antenna or cable system is grounded so 

as to provide some protection against voltage surges and built up static charges. Article 810 of the National Electri-

cal Code (U.S. A.), ANSI / NFPA 70 provides information with regard to proper grounding of the mast and supporting 

structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of anten-

na-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode.
