17.  Outdoor Antenna Grounding - If an outside antenna is connected to the receiver, be sure 

the antenna system is grounded so as to provide some protection against voltage surges 
and built up static charges. Section 810 of the National Electrical Code, ANSI/ NFPA 
No.70-1984, provides information with respect 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 antenna discharge unit, connection to grounding 
electrodes, and requirements for the grounding electrode. See figure 1.
