Interesting... so electrical length is affecting gain and EZNEC supports
it--that will probably silence those who claim the physical length is all
important... ya suppose?

And the Zepp.

I am not sure what the folded section does for it.

Folding a 1/4WL vertical raises the feedpoint impedance.
Folding a 1/2WL vertical lowers the feedpoint impedance.

A folded 1/2WL monopole has about half the end-fed feed-
point impedance of an end-fed single-wire 1/2WL monopole.
About 1250 ohms Vs 2500 ohms for 20m with mininec ground.

EZNEC sez the folded 1/2WL monopole has a slightly lower
resonant frequency and slightly higher gain. (+0.07 dB)
