Television Antenna Connection Protection
• 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.
