Computer modeling may improve the design. It would be interesting to see
what does happen. Construction wise, and this I can not remember, if
elements are mounted thru the boom as TELREX did then extra mechanical work
needed for mounting of elements and possibly re-inforcing of the boom.
Hope Chuck gets needed manual and maybe he can provide info for someone to
