size of grounding conductors, location of antenna discharge
unit, connection to grounding electrodes, and requirements for
the grounding electrode.

attention to Article 820-40 of the NEC that provides guidelines
for proper grounding and, in particular, specifies that the cable
ground shall be connected to the grounding system of the
