Consider antennas like the 2 meter Isoploe that uses 1/4 wave tapered sleeves to very effectively address CMC issues. The only difference is the direction the cone is folded in with respect to the antenna and source. If the sleeve or radials are folded up, it turns the portion of the vertical radiator inside, into coax while the outside of the cone still bleeds off the CMC. Always try to remember the EZNEC software you are basing your opinions on has fibbed to you. Today we have 100% proof of this 90 degree inaccuracy on the phase indicated in the program through my collinear experiments. I'm still willing to debate this topic with anyone who understands the collinear phasing experiments in order to show how it proves all of the EZNEC models we have seen were completely misleading.
