Well I designed a working gamma for my Vector 4K. I called the son of my old antenna mentor, and he gladly came over and help me thru the hoops. He made it look easy, but he used some Maxwell math which will be over the heads of most and I won't be getting into that.
DB, the problem with this hidden gamma thing is not what we, or I for sure originally thought.
The antenna does not have a good bandwidth, but it shows a near perfect match. I could not make any more gain to speak of.

The model also works fine when I create it in Free Space, and I added the pattern and match for it without the mast in the PDF file below.
The Average gain is 1.001 = 0.01 dB for the FS model.
As I've said before, adding matching to a model either makes the gain drop a little, due loss and or improving the actual model...that is my best guess. Or matching has little to nothing to do with adding gain in most cases.
I asked Martin about the I-10K model and the funny looking pattern that I and another buddy on the Internet saw after adding a matching device to a model. He said large matching networks can do that, and he gave me a specific reference to study on the subject.
I spent all day and 1/2 the night on this project.
