combination to overturn.
Antennas Antennas
Outdoor Antenna Grounding : If an outside antenna
or cable system is connected to the video product,
be sure the antenna or cable system is grounded
so as to provide some protection against voltage
surges and built-up static charges. Section 810 of
the National Electrical Code, ANSI/NFPA No. 70, pro-
vides 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 dis-
charge unit, connection to grounding electrodes,
and requirements for the grounding electrode.
EXAMPLE OF ANTENNA GROUNDING AS PER
NATIONAL ELECTRICAL CODE
Power Lines : An outside antenna system should not
be located in the vicinity of 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 as contact with them might be fatal.
