IMPORTANT SAFETY INSTRUCTIONS
Outdoor Antenna Grounding — If an outside antenna is connected to the television equipment, be sure the antenna
system is grounded so as to provide some protection against voltage surges and built-up static 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 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.
