Hello Mark,

Perhaps I'm not perceiving your position on the EH correctly, but from your
discussions above and in your previous post, my perception is that you believe
the EH exists and can be tested, and your problem is only with the test
procedure.

Mark, my position is that the EH does not and cannot exist in the manner Hart
specifies, because there is no way that the E and H fields can exist in time
phase--the change in each field generates the other sequentially. Hart seems to
be unaware of this fundamental fact, and also seems to be unaware that no power
can be delivered with current lagging voltage by 90 degrees unless there is an
opposite reactance to move the phase away from 90.

Since power IS delivered to the so called EH, the lagging current due to the
series inductance must simply be compensating for the capacative reactance in a
conventional shorter-than-resonant antenna, thus bringing it to resonance.

I'm saying there is no such device as an 'EH' antenna.
