A nice page written by some amateur drawing wrong conclusions.

his logic coax cable would not shield the center conductor either
for example since the coax has to be open on both ends. He quotes a
lot of good information and then spouts conclusion that don't
follow.

The author of the page is one of the most respected amateurs, an
active consulting engineer, designer of the DX engineering Low band
line of active antennas, and widely published. I have read identical
conclusions in the IEEE Journal on EM.

The null of the loop is its best feature. We agree there.

I'm sure he is a great guy and knows a lot but that does not mean he is
right. What he states is against theory and experience. I will go with
what practical experience supported by theory over someone's preeminent
opinion.

His opinion is contrary to the theory of operation of electrically small
shielded (or unshielded for that matter) loops compared to electric
field probes (example single wire or dipole).

You possibly misconstrued what you read in the IEEE journal.

We just had a discussion about inductive noise probes for trouble
shooting problems. Maybe you missed that. It was discussed here about
using a small shielded loop to distinguish between magnetic fields and a
short wire probe to pick up electric fields. Now this past discussion
relates to very close local induction fields. This is the very situation
the author you refer to claims the shielded loop probe would be useless
as it would be no different than the voltage probe response. Well sorry,
these probes really work as advertised because I used them
professionally and successfully.

My experience building and using antennas also run contrary to what the
author you refer to states. My experience in antenna building is also
predicted by theory. Most other people have had similar experiences
using loop and dipole antennas.

Again I will mention that there is a difference between an inductive
field and a far field that is a propagating wave and that theoretically
there will be a significant difference in response between E and H field
sensitive antennas to the inductive but not the far field.
