ANTENNA
Outdoor Antenna Grounding
If an outdoor antenna is installed,
y
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 as death or serious injury
can occur. 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 (NEC) in the U.S.A. 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.
