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.
DTV Transition Advisory
The nationwide switch to digital television broadcasting was complete on June
12, 2009. Analog-only television sets that receive TV programming through an
antenna now need a converter box to continue to receive over-the-air TV. Watch
your local stations to find out when they will turn off their analog signal and switch
to digital-only broadcasting. Analog-only TVs should continue to work as before
to receive low power, Class A or translator television stations and with cable and
satellite TV services, gaming consoles, VCRs, DVD players, and similar products.
