IMPORTANT SAFEGUARDS
12 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, 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 electrodes, and requirements for the grounding electrode.
See example below:
EXAMPLE OF ANTENNA GROUNDING
13 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 or approaching such power lines or circuits as
contact with them might be fatal. Installing an outdoor antenna can be hazardous and
should be left to a professional antenna installer.
