Comments appreciated.

Reading:
the note "capacitance from shield to conductor is uniform around
circumference. The capacitance from the inner of the outer
conductor to the outer of the inner conductor acts entirely inside
the transmission line and has no effect on the external balance of
the loop. The conditions on the inside of the loop outer conductor
are isolated from the outside of the conductor due to skin effect
as described above.

I would add a precautionary that the isolation is not complete. There
are many instances of this in small signal designs that fail for this
very reason. I am not sure what you are saying and what you are
repeating because there is no close quote in your commentary.
