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. 70-1984 (Section
54 of Canadian Electrical Code,
Part 1) 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,
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.
