Hello Howard, Stan and I have been working with Tom and Jay to come up  with
the proper separation and for the design of the stack match.  Jay will also
build the high-power balun as well.

Alan,

I own two Optibeam antennas and they are a quality product made in Germany. 
I met Tom, the owner of Optibeam twice at the Dayton Hamvention.  As you 
probably know, Array Solutions is the U.S. distributor of Optibeam products.

Tom's design is easy to assemble and after the elements were identified for 
me, I was able to assemble about 90 percent of the antenna without sighted 
help.  The assembly is straight forward.
