PROTECTION AND LOCATION OF YOUR SET
16-1 If an outside antenna is connected to the television set, be sure the antenna system is
protected against voltage surges and built up static charges, Section 810 of the National
Electrical Code, NFPA No. 70-1975, provides information with respect to proper grounding of the
mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of
grounding conductors, location of antenna discharge unit, connection to grounding electrode, and
requirements for the grounding electrode.

16-2 Note to CATV system installer: (Only for television with CATV reception) This reminder is
provided to call the CATV system installer's attention to Article 820-40 of the NEC that provides
guidelines for proper grounding and, in particular, specifies that the cable ground shall be
connected to the grounding system of the building, as close to the point of cable entry as
practical.

17 An outside antenna system should not be located in the vicinity of overhead power lines or
other electrical lights 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 as contact with them might be fatal.
