Spent some time today working on this dish. Firstly moved it couple of meters West thinking that neighbor's house will not be on the way to birds, I was wrong.... it does not allow to get decent signal from 45*E and 42*E also partially obstructed. But on other satellites got good results. Unfortunately do not have free 1/10 Diseqc, so if I need to switch to another satellite I go out and reconnect F-connector. Will probably do tests satellites one by one. I also see that there is a potential to install 2 additional.... no, I will not do that.
Very nice, but what I don't understand is: All your LNBs seem to havin roughly the same alignment.
If the dish is toroidal, then surely they should fan out from east to west?
I mean, this is like your discussion about "le point G" of the offsets; only in the vertical direction...
So, the question is: "Where in the horizontal plane of the toroidal dish should the LNB be pointing???"
...or is the answer that it's not that important, as long as the wavefront is funneled into the LNB feed tube?
