19.
Avoid
power
lines-
Use extreme care when
installing an outside antenna system
to
keep from
touching
power
lines
or
circuits, as contact with
them may
be
fatal. Do not install external antennas
near overhead
power
lines
or
other electric light
or
power circuits,
nor
where an antenna can fall into
such circuits
or
power
lines.
20.
Ground all outdoor
antennas
- If an external
antenna
or
cable system is connected
to
this
product, be sure
the
antenna
or
cable system is
grounded. This will provide
some
protection against
voltage surges and built-up static charges.
Section 810
of
the
National Electrical Code ANSI/
NFPA No. 70 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
ground electrode. Refer
to
the
