If an outdoor antenna or cable system is installed, follow the precautions below.  
An outdoor antenna system should not be located in the vicinity of overhead power lines or other  
electric light or power circuits, or where it can come in contact with such power lines or circuits.  
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.
