"Richard Fry" wrote So back to rote:
The physical size in relation to wavelength dominates launch
characteristics, NOT electrical length.

I don't know who wrote your rote, but here is part of what Terman
says on
this topic in his Radio Engineer's Handbook, p 795, referring to
vertical
radiators driven against ground:
"Top loading has the same effect on the field distribution in a
vertical
plane as a greater height. Thus an antenna for which H = 0.45
lambda can by
suitable top loading be made to have a field distribution in the
vertical
plane that is substantially the same as for a vertical wire of H =
0.6
lambda."
=============================
No, it doesn't !
But you could stretch "substantial" (a non-engineering term) a bit
more.
You have been warned once before about quoting Terman as the Bible.
