  Sure. But you can't accurately model ones made with twinlead or window 
  line, since NEC-2 or EZNEC can't account for the effect of the 
dielectric.

 Okay, great! 
 
 I modeled a folded monopole at 434 MHz. Varying the length down from 
 resonance, the element showed the terminal impedance getting lower in 
 resistance and become increasingly capacitive just like the unfolded 
 monopole. 
 
 I thought it was supposed to be backwards from the usual unfolded monopole 
 such that it would go up in resistance and become inductive.?.

Did you go down to 217 MHz and below? If not, check it out. Should hit 
another resonance at something like 50,000 +j0, and stay inductive below 
that.
