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/NAPA
No. 70-1984, 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 the
National Electrical Code example below.
Lighting – For added protection for this video
product during a lightning storm, 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.
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.
