Richard,
If your current is different at the ends of the coil, you're an angel.


The question that leaps to mind is how are you going to replicate the
data if you were so ignorant of the original details? Even more, it
would further all discussion for you to offer a COMPLETE specification
of what you are doing (or going to do), rather than an informal ramble
around the garden with a camera.


The point of the original argument was: is the current the same or different at
the ends of the typical coil in loaded antenna. I will reiterate the exercise:
I knew it was different from my "heat tests with Hustler", W8JI countered "you
dummy, it can't be" (in a nutshell :-), ON4UN showed graphically how, W9UCW
chimed in "it is, I measured it, here is some data", Cecil theorized it, W8JI
chorus "calculated" it can't be.

My point is that I argued that current is different, not how precisely I can
calculate or offer calculated "proof", the first order was to convince
unbelievers that there is a difference and let them loose to figure out why
(Cecil shined light on it) and then to properly apply formulas and figures so
we can model it.

So when I say that I want to do MY measurements, I am not after exactly
duplicating W9UCW measurements and test, I just want to pick, first my mobile
antenna (practical situation) and then similar setup what Barry used - nice 60
radial ground plane and various loaded radiators and see what (formulas,
software) comes close to reality. We are already seeing some path, and with
sliding current probe I believe I can get more data along the radiators and we
can see how does it jive with Barry's and with calculations and modeling. So
again, I am not after replicating Barry's laboratory. If what we are saying is
true, than it doesn't matter how fat the coil is, where it is within the
limits, more data from various situations will help us to correlate the
procedures. My goal was to convince unbelievers (and as we can see, there are
plenty), well, to show that current in a typical loading coil's ends IS
DIFFERENT (it is up them to believe it or not).

This wasn't on the level of scientific conference paper, but more like a street
fight - who is right and why are you ridiculing me (us) if I am (we are) right.
Now roll your slide rule blades out and lets do the stage two, fine tune the
"theory" and put some good numbers on IT.

So she's round after all? Should we change thread name now?
