Important safety instructions
Outdoor antenna grounding
If an outside antenna or cable system is connected to your TV combo, make sure that the
antenna or cable system is grounded to provide some protection against voltage surges and
built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA No. 70,
provides information with respect to correct grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors,
location of the antenna-discharge unit, connection to grounding electrodes, and
requirements for the grounding electrode.
An outside antenna system should not be located near overhead power lines or other electric
light or power circuits, or where it can fall into such power lines or circuits. When installing an
outside antenna system, extreme care should be taken to keep from touching such power
lines or circuits, because contact with them can be fatal.
