TELEVISION ANTENNA CONNECTION
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.
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.
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.
