[TowerTalk] Why radials improve radiation!

An end fed zepp is kinda like a J-pole stretchd out straight. That's why a 
certain length feedline works best.  73

What about an end fed Zepp?  Fed with open wire.  I have read that it thinks
there is an immaginary 1/4 wave section where the feeder is terminate at a
dead or insulator point.  I know this is a high impedance point on a zepp.
A half wave vertical would need no radials  on that resonant frequency.
