10. Outdoor Antenna Grounding
If an outside antenna or cable system is connected to the product, be sure the antenna or cable 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.
11. Power Lines
An outside antenna system should not be located in the vicinity of overhead power lines or other 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 such power lines or circuits as
contact with them might be fatal.
