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
electrode, and requirements for
the grounding electrode.
16-2. Note to CATV system installer:

reception). This reminder is
provided to call the CATV system
installer s 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 building, as close
to the point of cable entry as
practical.
