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.

Note to CATV system installer

This reminder is provided to call the CATV system installer’s attention to Article 820-40 of the

NEC that provides guidelines for correct grounding and in particular, specifies that the cable

ground must be connected to the grounding system of the building as close to the point of

cable entry as practical.
