[TowerTalk] ground radial length vs antenna height?

[David Jordan]

What is missing for me on this article is at what take-off angle is the
increased efficiency realized?  I suspect the smaller radial systems raise
the angle of radiation slightly or maybe not so slightly.  Who knows?

...N6LF has also published some excellent work on radial systems. It's 
on his website. Google to find it.
