Television Antenna Connection Protection

External Television Antenna Grounding

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.
