I understand that E and H fields are intrinsic parts of the same thing (for
radio waves, etc), and I am not trying to separate them along the lines
discussed by some list participants.

I would think that the E and H ratio of 377 is a function of the SI units of
measurement involved. It would seem that there is the same amount of energy
(at different and selected instances) in the E and H waves, and different
units of measurement could produce a ratio of 1:1 (or anything else, with
appropriate units of measurement).

To return to the ferrite rod antenna: Ignoring the directional null
capability (which might be very useful in some real-world circumstances) is
there any advantage to a small ferrite rod antenna over a short wire antenna
(assuming perfect amplifiers, as needed, following the antennas and assuming
160m or 80m usage)?

As mentioned earlier, there have been a number of construction articles over
the years explaining how a ferrite rod antenna did wonderful things for
160/80 operation. I have wondered if these results are generally valid, or
were the result of the authors' pride in their works, or happened because
the directional null abilities solved a local problem.
