IMPORTANT SAFETY INSTRUCTIONS
(Continued from previous page)
14. Outdoor Antenna Grounding
If an outside antenna or cable system is connect-
ed 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 grounding electrodes, and
requirements for the grounding electrode.
