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.
