I mean no offense but everything you said is complete hogwash once again and NONE of it can be replicated in the field. How does this end fed antenna differ from all the rest and have no CMC current like you suggest??? Since that's not possible tell us why you think the CMC would be drawn to another point rather than the resonant 1/4 wave cone?
Since you're now willing to admit the cone feeds the 1/2 wave radiator above it, it should be just as obvious to you this end fed 1/2 wave must produce CMC at its feedpoint which is the top of the cone. It must flow back down the outside of the cone because there is no other path. I'll remind you once again when the cone is not properly tuned CMC is noticeable on the coax. Hint!
Do me another favor and stop telling me I can't show proof the base of the Sigma radiates significantly. The reality is you don't have the ability to replicate the test required to prove yourself wrong or you're not willing to try going beyond words like those of us who have taken the time to obtain the hard evidence themselves.
Donald has already proven every thought you have about the Sigma wrong. Proof takes work Marconi, that's why you don't have it in this case. Since success in my job required it, I did the leg work necessary to identify the phase and magnitude of the cones radiation. The only details you need to know about the currents in CST are displayed in the 1/2 wave shape of a 1/4 wave current in the cone.
The one detail behind everything about the 90 degree phase shift taking place in this non apparent collinear. To remain in denial and keep the debate going you MUST ignore this fact and dismiss it as an anomaly or error in this program. Besides, according to what we've seen in the past from you, you'll just say CST is wrong or claim another anomaly.
You're too hung up on getting your hard evidence so don't pretend some current log from Sirio is going to stifle your misinformation now. The only way to get the hard evidence that your theory cannot be replicated in the field is to do the collinear field tests. That would without question prove everything I've claimed but you'll never do this or get someone you consider unbiased to do it for you prior to sharing the inaccurate humble opinions you do. With that in mind, don't ask me for more proof until you're willing to use the undisputable test I've already provided you with in great detail.
