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.
EXAMPLE OF ANTENNA GROUNDING
16-2 Note to CATV system installer: (Only for the television set 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 this television set during a lightning storm, or when it is left
unattended and unused for long periods of time, unplug it from the wall outlet and
disconnect the antenna. This will prevent damage due to lightning and power-line surges.
