Just a note to consider: Here is my Starduster in the background and my Marconi with a GR45 mobile antenna with a top hat in the foreground. I asked earlier for your radial dimensions, so I thought I would show you the difference instead.

The Marconi setup uses a homemade GPK hub using three 102" whips with a 27* degree angle. The Starduster comes with an angle that is <=20* degrees. I know for comparison purposes these pictures are not in perfect scale, and there is likely some skewing, but I think you can the idea that there is a little difference in the radial angles. Based on my real world experience and my modeling I believe the sharper angle down makes a difference in gain that is detectable. It is not a big huge difference, but it does show to be better.

I have a stock Hub with 4 radial ports, and I added 4 ports to the horizontal side of the hub, but it does not work as good as my 3 port hub with a sharper radial angle slanted down. I can detect the difference using my radio.

I also have two old styled M400's knockoff's that I picked up over time and they too did not work as well as my Starduster or my Marconi. I think this is also due to their angles being closer to about 40* degrees like your setup looks to have.

I'm not real sure, but I think the Merlin that looks like a Starduster antenna uses a radial angle that is closer to 40* degrees as well.
