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.
