Why would it do that?

Well, you said earlier that the folded monopole could be modeled as an
unfolded monopole with a shorted transmission line in parallel. I thought I
understood. When I modeled the unfolded monopole, I saw it do as usual when
the element was varied in length. But when I included the shorted section of
transmission line and varied it directly with the element, I thought I saw
the terminal reactance go inductive as the length was decreased below
1/4-wave resonance and I thought the terminal resistance went up. So, I was
expecting the same from EZNEC by modeling the folded version.

I guess I'm really lost here.

John
