Does anyone have the dimensions for either or both JoGunn's? I would like to model them?

 

I have a make-shift model I made of the SofG which may not have exact dimensions. I'll look and see if I kept it in my file. If so, I'll post what results I have, but I don't recall it only having a high maximum angle of radiation and/or no worth while gain at some lower angle that is not the maximum.

 

SW in case you missed it in my previous post above, do you want my new file for the Sigma 4? I know that you asked Henry for one. I have the same file and I can send you Henry's New model or my modified version that is  from the same file...showing some nice gain at a low angle instead of very little gain at a high angle.

 

Henry says he did not work to improve the file, he is working on a new 40' co-linear monopole with some real gain at a low angle.
