You'll probably find a common error in broadband system
installation by looking at your own home or one nearby that has
broadband service to the structure. This same problem exists
today in many facilities that would solve mysterious failures if
they would fix this Code violation.  The requirements in 830.93
refer repeatedly to grounding and, in this context, that is
correct. But it's not the whole story on the requirements, and
unfortunately grounding is where many installers stop.  When you
read Part IV of Art. 830, a more complete picture emerges. If
you were to draw that picture out on paper, you would see a line
running from the broadband grounding electrode to some point on
the main grounding system. That is, it connects to the
Intersystem Bonding Termination (defined in Art. 100).  But if
you already have a ground rod on your broadband system, what's
the point of connecting it to your main grounding electrode
system? The point is to eliminate a difference of potential
between these systems. For a deepe
