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. Section 810 of the National Electrical

Code 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.

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.
