Modeling wont work. This antenna uses multi coax sections folded and placed inside the tube, with the feed point at the mid point, and section dropping below the tube with the coax connector. So far I have found no one that has the spects for all of the bands. It covers 80 thru 10 meters (less 160 and 60 meters). It is a great antenna, I would just like to know more about it.
Hope someone out there has de-structed one and figured how it is put togethere and has some written data stored away somewhere.
