Well Bob, the model was a surprise to me, so I want to take some more time and see if I missed something.
Here is the Free Space model I started out with so we could see what Exnec says about accuracy.
1. The first page is the control page for Eznec showing the Free Space results for the Average Gain which shows 1.003, very good.
2. The next two pages show a close up and at the bottom each page show the dimensions for the radiator wire #2, and the radial wires #7,8,9,10.
3. The Free Space pattern which is a surprise to me. Does this remind you, a little, of something that you have reported about your Vector Hybrid?
4. SWR curve showing the bandwidth. This too surprised me, but it is what I was watching for in this model as the only real gauge I really have to compare to published reports about models.
5. The Source Data report showing a very good match.
6. Is and overlay comparing my recent model of the New Vector 4K to specs and matched. I didn't expect this, but I don't see the performance reported for this antenna, unless you want to just consider the very nice bandwidth.
To me this wide bandwidth confirms what is reported in the science, if we see more bandwidth we should not expect to see more gain. This is why I had my doubts.
