Yep BM, I could have included hams too, but my point in saying that was to draw attention. It was an "attention getter."
I'm going to redo those test, Marconi's Eznec5 model - Imax with radials at various angles, just because I found that the face model with horizontal radials was in error with the radial length. I made it with 62" radials instead of 72" like the original GPK comes. I don't know if I made further mistakes in the models I posted, but I know all the dimensions I used for the recap work were done one steps at a time at 40', 65', and 36' feet using the exact same model each time. I just posted those 4 Eznec models to kind of support what I showed in the recap report.
I don't think this will make much difference in the results, because the model with horizontal radials is better when corrected that the model I posted, so the result differences are probably even more obvious when using horizontal radials on the Imax.
I don't know off hand how the models for the Imax and SP400 differ, but if I can think of it, I'll check that for you. I never did get my model of the SP400 with a working matching device included...to working right, so I'll compare a regular 5/8 wave ground plane at 22.5' model instead, and we'll see what Eznec says about it, OK?
