DB, If you have an alternate theory of what's going on, I'm more than eager to hear it when you're ready. My only concerns are the new theory should represent the collinear field tests with a 90 degree delay and should explain the odd shaped pattern that I believe CST is showing as a result of the 90 degree offset in two currents on the cone.

I recognize the significance of having to confirm the 90 degree phase delay as functional in the field first and assume you understand how that required phase delay in a collinear version helps us to not only identify the cone is radiating constructively but to also helps identify the odd radiation phase the Sigma forms.

I feel this is a logical conclusion since you can't constructively stack another collinear radiator on top without correctly identifying all of the radiated currents of the existing antenna to predict the required phase shift to drive another section.
