Topband: Cone of silence

Just one quick comment.

I can't think of an easy accurate way to measure radiation
from a vertical antenna end. If the antenna is terminated in
a center tapped "T", the T wire used as a "non-radiating"
counterpoise wire picks up nearly as much signal as the
vertical section!

The only way I can think of to measure end effect would be
to use perhaps a dozen elevated radials in the termination.

Maybe someone can model the antenna both ways and compare
the patterns.
