Homer, I just described my further findings with my best model for the A/P and when I submitted it, the Internet browser closed down on me. This happens all to often, but what can we do?
So, I'll try again and send the models along with the original working model, one set with the strap -1" lower and the other with the strap set +2" higher for a total of 3" in range. They react just as you describe above, and this time I moved the strap. I put notes on the models.
I don't think the original was designed to move the strap or you would loose the securing mechanism for connecting the two 48" radial elements. I also found the radials on the original model were a few inches longer, 93"-94", than the Top One I have at about at 89.25".
I also think Avanti set this strap point at the best spot, so there is no need to tune. Just install it where it belongs, no measurement. If we want to tune this one I think the top hat radials will do that just fine, but I'll have to check out how that responds for the match.
Your words above cleared up some issues for me and I thank you.
I did a model with the radials straight and that shows the model needs the bow to get the better match. I have included an overlay, but I forgot to include the model with straight radials.
