•  If an outside antenna/satellite dish or cable system is to be connected to 

the TV, make sure that the antenna or cable system is electrically grounded 

to provide some protection against voltage surges and static charges. 

•  Article 810 of the National Electrical Code, ANSI/NFPSA 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 the grounding conductors, location of antenna discharge unit, 

connection to grounding electrodes, and requirements of the grounding 

electrode.

•  Lightning Protection: For added protection of the TV during a lightning 

storm or when it is left unattended or unused for long periods of time, 

unplug the TV from the wall outlet and disconnect the antenna or cable 

system. 

•  Power Lines: Do not locate the antenna near overhead light or power 

circuits, or where it could fall into such power lines or circuits. Remember, 

the screen of the coaxial cable is intended to be connected to earth in the 

building installation.
