I have never found this to be true so I did a quick model and EZNEC shows 
that a .28wl vertical has an SWR of over 3:1.

Gerald,

I disagree.   If a quarter wave vertical or ground plane is lengthened to 
about
.28 wavelength, the radiation resistance raises to about 50 ohms and a 1:1 
SWR.
 It is not resonant, but it has a lower SWR than a "resonant" antenna.
