Well Donald, I haven't tried to diagnose all this yet. The big job was trying to make sure that the models were pretty close in segmentation. I noticed this technique once in a article that Cebik published...where he gave enough data that I could actually duplicate his results. I just tweaked the segmentation values to get close to his results, and I began to see how he handled segments. I figured out with 500 segments available in my version of Eznec...that I can use the following scheme: wire length" / .25 in inches, wire length' / 3 in feet and everything works out pretty good.
Maybe I'll go back and do some free space patterns for all of these models, but with verticals models we don't see much ground reflection like Gary Wescom N0GW, suggested in his link on 211's thread on TOA.
He was also using horizontal models, and that might be confusing these guys if they try to interpret what his ideas are about and don't know there is a notable difference in patterns. I can't say Wescom is wrong, but horizontal patterns are entirely different in many respects from vertical patterns.
He is also discussing much lower frequencies for the most part, and IMO, operations there use different techniques to communicate, and some of that stuff does not directly relate to CBr's vertical polarity world...in a practical manner.
Just my thoughts on the subject, and I don't even like discussing TOA because the subject is so technical on the one hand, and then subjective on the other.
