PROTECTION AND LOCATION OF YOUR TELEVISION
16-1 If an outside antenna is connected to the television , be sure the antenna system is grounded so as to
provide some protection 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.
EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL CODE INSTRUCTIONS.
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.
18 For added protection for the television during a lightning storm, or when it is unused for long periods of time,
unplug it from the wall outlet and disconnect antenna. This will prevent damage due to lightning and power-line
surges.
