14. Outdoor Antenna Grounding
If
an
outside
antenna
or
cable
system
is connected
to
the
product, be
sure
the antenna
or
cable
system
is grounded
so
as
to provide
some
protection against voltage
surges and
built-up
static
charges.
Article 810 of the National Electrical
Code (U.S.A.), ANSI/ NFPA 70 provides information with
regard to
proper
grounding
of the
mast
and
supporting struc-
ture,
grounding of the lead-in wire to
an
antenna discharge
unit,
size of
grounding conductors,
location of antenna-dis-
charge unit,
connection
to grounding electrodes,
and
requirements for the grounding electrode.
15. Lightning
For added
protection
for this
product (receiver) during
a
light-
ning
storm,
or
when it is left unattended and unused for long
periods of time, unplug it from the wall outlet and disconnect
the
antenna

This will
prevent damage to
the

surges.
16. Power Lines
An outside antenna
system
should not be located in the

fall into such power lines
or
circuits. When
installing
an
outside

extreme
care
should be taken
to keep
from
touching
such power lines
or
circuits
as
contact with them might be fatal.
