Hi!
I have original feedhorn for Prodelin antenna. I think that using that would be best option (maybe not). Problem is that not so easy to find flange LNB, and secondly that LNB will have 8 holes instead of 6 feedhorn has. Could be possible to use only 2 holes to join them together, but what if diameter of centers of those holes on LNB and feedhorn are different! Another option would be to find/make some kind of adapter (Vipersan just used). Third option and way I will probably go is to adopt universal LNB to be ready attaching feedhorn directly. I have found person who is doing such adaptations, see picture.
My question is: Which Twin LNB I would better chose to get maximal results.
My options by now following:

Would like to hear some elaborations on this topic.

A while back I created an Invacom feed/Inverto black ultra hybrid to mount a modified black ultra designed to fit on an offset dish on my PF dish ..
Sadly although I can find the thread ..the pics have all gone..
But I see no reason why something similar can't be done to fit your Prodelin feed to a black ultra ..
It works well ..and is one of the better mods I did.
Here is a pic of the combo ..

I have a c120 flange for the BU adaptation. I'll take some measurements and post them here if you want to test it? Though I don't think it's a big job to create the flange yourself as VS demonstrated.
 
I am not ready to produce adapter needed. I mean technically. Anyway I need to go to specialist or buy something like this internet-sat-shop.de/shop/product_info.php?products_id=2796&osCsid=d0d0ca62e21b1d38e0f775538ab836a0
Secondly, I do not like idea that I have only one choice which is Invacom flange LNB. I have some bad experience with this brand, so, do not considering it as best one IMHO. And it is 2x more expensive as well. In this case, my choice would probably be Twin Micro New Gold edition, like t's shape and color, and hope it has good electronics in. And friend of mine will make it flanged already with proper flange. That is the plan.
Of course, it is also possible that after making this new LNB and using original feedhorn, results will be worse than I have now with Black Ultra LNB.
There is always risk, but so what? :rolleyes:
