It should be possible to broadband your vertical using lumped element
circuits at the base.  You would need to model or measure the base 
impedance vs frequency and then find the element values by trial and 
error with a modeling program like SimSmith.  Somewhere in the past, QST 
had an article about this in "technical correspondence" that related to
dipoles.  That would at least get you started.

Dan:  can AUTO-EZ do this optimization?
