12. Outdoor Antenna Grounding—If
an outside antenna or cable system is

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,
ANSI/NFPA 70.
Example of Antenna Grounding
13. Power Lines—An outside antenna

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.
