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.?.
