Perhaps then you'd care to describe more fully the steady state condition
wherein the canceled waves are not canceled?

now lets really have some fun with the cancelled wave and disappearing
energy crowd that redirects power from here to there and sloshes it back and
forth so it doesn't go anywhere.

This is after all an antennas group, so lets take a real antenna. I have 2
160m verticals that are 1/2 wavelength apart over a pretty darn good ground.
Now, I can feed them either in phase to get a broadside pattern, or I can
feed them 180 degrees out of phase to get an end fire pattern. Everyone
here should agree that this works as it has been well demonstrated over the
years, and even nec predicts it so art should be happy.

Now you may ask, why is this any big revelation... well, because it is a
perfect example of waves that cancel but don't disappear, slosh, or get
redirected anywhere. consider the case where the 2 verticals are fed 180
degrees out of phase. on a line 1/2 way in between them and perpendicular
to them there is perfect cancellation of the two waves... and yet, you can
move just a little bit off this line of symmetry and viola, the waves are
both there and add as expected. in fact if you walk from one vertical to
the other and keep on going on that line you will come to the center point
where the waves perfectly cancel, then keep walking and just 1/4 wave later
when you get to the next vertical, and everywhere from there on the two
waves add together.

Now how does that happen?? is there some kind of magical reflection field
set up so that no power can cross that midpoint line?? maybe this is the
first evidence of a star trek type forcefield that magically deflects
phasors while still letting you see the photons?? So where does the power
go??? at that mid point E=0, H=0, ExH must also be 0 at all time, and
everywhere along that symmetry plane... so how can the waves add up again on
the other side? quantum tunneling? art's magical levitating cosmic
diamagnetic particles??? virtual photons?? oh, I forgot, these verticals
are copper clad steel, doesn't the steel mess them up or something because
the cosmic particles fly away? or is the thin copper enough to let them
settle on an otherwise insulated slippery vertical surface??

I know what the equations say... I also know what the contest results say...
the waves keep going, and going, and going... and the qso's keep coming, and
coming, and coming. So lets see how well art's magical mystery antenna
plays in the ultimate 160m contest this weekend... how about it art, I'm
sure everyone would love to see you prove your little antenna can out play
something bigger??
