It looks likes that the spacing between conductors needs to be quite a bit less than I was estimating. This makes building the antenna significantly easier than first thought. After searching the web I found nothing at all relating to the calculations needed to determine spacing. Also very impressive webpage you have. Thank you for having an English version.
