The challenge for Cecil's model is to explain how the antenna does
behave. This cannot be done by reclassifying the type of antenna, or
reclassifying the type of current through the loading coil.
I'm not reclassifying anything. The differences between traveling-wave
antennas and standing-wave antennas have been known for many decades.
Oh good! Exactly where do *you* draw the line between them; and why?
Please justify this by giving examples of two antennas that are very
close to your chosen line, but on opposite sides.
Then please justify the difference between your two different
classifications of current.
The problem that some of the gurus on this newsgroup have is that they
have forgotten everything they ever knew about standing-waves and
standing-wave antennas. You guys worship your shortcuts to such an
extent that you have completely lost touch with reality. W8JI's 3 ns
delay through a 100T coil on 4 MHz is just one example. At least a few
posters are beginning to understand why W8JI's measurement was
invalid.
As you are so fond of saying, the technical content of that is duly
noted.
