Dear Dick, LF Group,

I drew some rather similar pictures myself, and got an identical result -
but the final configuration we both arrived at is different to Figure 2b
from the article, in that the top load section is connected to one wire of
the stub, while the power source is connected to the other. In the
configurations in the article, the power source and the top load are both
connected to the same stub wire.

Incidentally, your "topload3" diagram is more or less W4DEX's antenna
configuration, I think.

Cheers, Jim Moritz
