• 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.
