15. Outdoor Antenna Grounding – If an outside

antenna or cable system is connected to the

product, be sure the antenna or cable system

charges. Article 810 of the National Electrical

Code, ANSI/NFPA 70, provides information

with regard to proper grounding of the mast

and supporting structure, grounding of the
