SAFETY INSTRUCTIONS 9 ANTENNA Outdoor Antenna Grounding yyIf an outdoor antenna 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 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 leadin 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.

Outdoor Antenna Grounding
y
If an outdoor antenna 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 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.

Code (U.S.A.). The code provides
guidelines for proper grounding and,
in particular, specifies that the cable
ground shall be connected to the
