Mike,  
Over the years I have come to know Don as always succinct and to the point.
AND, he does know his stuff nearly 100% or he will not comment.  He will not
waste his time responding to this accolade.  We go back to the K2 field test
and he was much a pleasure to work with then as now.  Oh, I and I think his
knowledge and writing skill has improved with age!

73,
Bill

The concise clarity of Don's input to this thread is refreshing.  Such seem
to occur rarely in ham discussions about antennas.

With respect to classical end-fed half-wave antennas, I think of the end-fed
Zepp[elin] and the common VHF J-poles.
