Electric Service Equipment

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.
