I will check Blender out. I tried doing screen capture video with my Logitech, but tracking that was a beast. Your video is slick and is just what is needed to capture my desktop view for a video.




No, I thought about it, but first I wanted to see if you could confirm my claims. I wasn't sure it was just the way I modeled my I-10k adding a physical matcher to the mix. Your suggestion for checking the AVG is probably the best way to test our segment decisions.




Yes, using the matching network idea instead of adding the physical matcher, like I did. This is not about using the optimizer.


When I first tried adding the trombone matcher to my I-10K model I thought doing so would possibly show better results and maybe be more accurate. Now, I don't think adding a physical matcher to a model is a good idea. However, I would still like to know what you find, in this regard, using the 4Nec2 software matching feature.




I take you word for this one. I haven't tried this with Free Space models yet. I also notice, and maybe you can see this in the models I just posted, that as the segment count get lower in numbers the red "O" indicating the Feed Point also changes in relationship to it normally assigned location, and IMO this too may be a play in what we see here.




I agree, so for me this conversation has shed more light on my approach to modeling, and when I learn something new...it is a good day.




Can you optimize using AVG as a goal for success?






DB, I have to start modeling using 4Nec2, for me to do something similar I have to use trial and error, write down the results as I make changes, and then try and analyze what the data shows.


I'm not in the weeds with my math skills, but I'm not a math man either. Do you think I can master the seeming complicated code to setup the optimizer and use the geometry editor that you use?




Like I said above, if you check the FP out as noted on my Antenna view, and look for the segments set at 10/.50w vs. 50/.50w you will notice the FP is not anywhere near the point it was set at on the antenna compared to the model I originally made using my segment scheme of approximately 3" inches per segment.


The 10/.50w ratio above would generate a segment length of about 43.2" inches per segment, and the 50/.50w would be 8.64" inches per segment, while my model is set at about 3" inches per segment.

                                                                                                          



Your work here suggest what I recall reading in the Eznec manual where Roy Lewallen posed below. He told us that segments were very important to the success of a model. You will also note some similar words in the manual that you suggested above.




I agree
