Did you also check out the construction article at http://www.qsl.net/dk7zb/zigzag/zz-construction.htm
Not quite sure where you got "9:1" from as it looks to be a standard 4:1 half wave coax balun arrangement in the article, unless you add all of the extra sections (eg 10 el) to cause the feed impedance to rise.
