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
(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
16 Lightning—For added protection for this
video product 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 or cable
system. This will prevent damage to
the video product due to lightning and power line
surges.

IMPORTANT SAFEGUARDS
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.
