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 .

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 l ines or circuits . Remember, the screen of the coaxial cable is
intended to be connected to earth in the building installation .
