nected to the receiver, 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

spect 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. See figure below.
