What you say is true, but I agree fully with Tom's comments on the 
slovenly work coming out of the U of RI.  The early claims were simply 
ridiculous and unsubstantiated by mathematical analysis.

In the first place, any technical acedemic who is too lazy to search the 
paper archives should probably find another vocation.  More importantly, 
the lack of easy access to some of the older studies is more than offset 
by today's easy access to powerful modeling software.  Even ten minutes 
in front of a computer running almost any version of NEC will 
demonstrate the near field strength parity of a 1/8 wave vertical versus 
a full 1/4 wave when both are over a perfect ground.  The Navy's test 
results were a foregone conclusion and a big waste of somebody's time 
and our money.

I can understand an individual like Vincent coming up with wild claims 
for the publicity of it.  I have a harder time understanding how a major 
university goes along with it unless they simply don't know any better.
