Yes Homer please post your results. I'm just looking for the truth of this matter concerning our AstroPlanes.

Quite often I see things that click with my ideas and understanding using my models and considering my experience, but with my modeling...most often not so much. I can't predict the gain and angle for any antenna, and that is what most guys look for and want to know. With that part of my modeling, I just take what I get and report accordingly.

I found recently that some of my models will allow me to model a seemingly effective matching system based strictly on the physical appearance and dimensions. Accuracy seems to be the key to success, and that effort only works when no tuner is required or when the required tuner is inductively in series...similar to your .64 wave maybe or my Starduster. When this happens, I have expectations that the model possibly should act similar to the antenna in the real world at least regarding the match, SWR, and bandwidth. Of course I have to also consider there is usually a feed line involved in the real world testing, and that alone might be problematic regarding my getting similar results. And when all is said and done, no two installations are likely to produce the same results in real world testing, so other's mileage may vary.

So, in this case any information you have will be helpful for me. I hear a lot of bad news about modeling, it's about time for some good news, and I'm thankful whenever it happens.

Thanks for your help.
