If an outside antenna or cable system is connected to the device, be sure the antenna or
cable 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 (Section 54 of Canadian Electrical Code, Part 1) provides information with respect
to proper grounding of the mast and supporting structure, grounding of the lead-in wire
to antenna-discharge unit, connection to grounding electrodes, and requirements for the
grounding electrode.
An outside antenna system should not be located in the vicinity of overhead power lines,
electric light or power circuits, or where it can fall into such power lines or circuits. When
installing an outside antenna system, extreme care should be taken to keep from touching
or approaching such power lines or circuits, as contact with them might be fatal. Installing
an outdoor antenna can be hazardous and should be left to a professional antenna installer.
