13 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.
14 Do not overload wall outlets and
extension cords as this can
result in fire or electric shock.
15 Never push objects of any kind
into this television equipment
through openings as they may
touch dangerous voltage points
or short-out parts that could
result in a fire or electric shock.
Never spill liquid of any kind on the
television equipment.

Electrical Code, ANSI/NFPA
N0.70-1984, 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.
