Topband: Ground mounted 1/2 and 1/4 wave verticals (was GAP)

[Bill Aycock]

Gentlemen--
I am learning a LOT, but there is a Great Deal of confusion (at least in my 
mind) because at least three quite different conditions are involved.
We have the base fed 1/4 wave vertical; the base fed 1/2 wave vertical; and 
the center fed 1/2 wave vertical.  Grounding considerations are very 
different.
As far as I know, even though the same analytical tools are pertinent, the 
characteristics and the design approaches are quite separate.
Please, try to clearly separate them in these discussions, to help people 
like me.
