1 2 . Outdoor Antenna Grounding-If
an outside
antenna or cable system is connected to the product,
be sure the antenna or cable system is grounded so as
to provide some protection against voltage surges
and built-up static charges. Article 810 of the
National Electrical Code,
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 as per National
Electrical Code,
70.
Example of Antenna Grounding

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.
