"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.
