Grounding
If an
outdoor antenna or
cable system is
installed,
follow the
precautions
below.
An
outdoor antenna
system should not be
located
in the
vicinity of overhead
power lines
or other
electric
light or
power circuits,
or where it can
come in
contact with
such power lines
or circuits.
WHEN
INSTALLING AN
OUTDOOR
ANTENNA
SYSTEM,
EXTREME
CARE
SHOULD BE
TAKEN TO KEEP
FROM
CONTACTING
SUCH
POWER
LINES
OR CIRCUITS AS
CONTACT
WITH
THEM IS
ALMOST
INVARIABLY
FATAL.
Be sure the
antenna system
is grounded so
as to
provide
some
protection
against voltage
surges
and built-up
static
charges. Section
810 of the
National
Electrical
Code
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.
