Feedpoint impedance does change. But, what has that to do with resonance??

I may have inferred from Roy's posting what he didn't mean
to imply. Here's what I assumed he said: "The *feedpoint*
impedance of the antenna doesn't change with the feed
method." I hope you agree that is a false statement but
may not be the meaning that Roy intended. I apparently
made the same mistake for the meaning of your posting.
If you guys would just post in Texan, I could understand
you. di-di-di-dit---di-dit

If Roy had said, "The radiation resistance of an antenna
doesn't change with the feed method", I wouldn't have
questioned it.
