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

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