Tim, About ten years ago I did some optimizing on the 155ca using YO
software. I still have the software but its not loaded and is a DOS based
program. I can check through my files as I know I never throw away any
antenna files. I should still have the spacing and tapper schedule if you
want them.
My modeling was for a single antenna and did not model it as a stack so not
sure how it would behave in that environment. The antenna worked very well
and I sent my findings to Hy-Gain and Roger (do not recall his call) wrote
back and said he really liked the results but they would stand pat on what
they were using.
