I do forget sometimes Bob, but as I said...I am not perfect. Your personal attacks are not convincing.
Bob, it is you that doesn't remember now. When the collaboration was going on it was long before I ever disagreed with what you said. When I did my S4 testing in the case you never talked about what I was doing because you could only have guessed, and that was also long before I ever posted a video. That, my friend is the recollections I correctly claim...and you can only deny it never happened. Among other things, the primary thing I learned back then from you was our discussions about transformation. You were disappointed that I could not report the results you promised me that I would. In the end you told me that the old S4 was not capable of showing the type of results you were reporting, and that is what disappointed me. If that is not what happened...then the truth is not in either of our words.
I admitted to DB that his report about his 4Nec2 Vector model showed results similar to what Donald and Sirio have reported for the New Vector 4000. I explained that if that was possible I could be wrong in my opinions on this issue, but you apparently did not understand my words. That is the convenience that I mentioned.
Those are my opinions. Why don't you show us how the sleeved dipole is of any benefit to the antenna performance over a plane dipole? I checked out the Sleeved Dipole model that Roy provided in his Eznec software as an example, and I don't see any difference in performance, none nada.
Again it is true those are my opinions ignorant (spelled correctly) or not. You could convince me otherwise if you would address the question above.
It could also be said Bob, that the ideas you have posted for us over the years are dubious at best. You can't be sure of any ideas for what Cebik told you, and I understand how that can happen. To consider complicated issues it takes time and communications between individuals.
Cebik gave you a hint why he did not want to discuss the S4 idea further...and you are helping to fulfill that prophecy. Now a dictionary may come in handy.
