Hmm, your last message is a bit confusing actually.
Anyway, so basically you say you get most C band channels from 26°E, cool. What about other satellites?
I find nothing whatsoever related to "nauxis" with either a google or
Ebay
search...
If you can indeed make a picture of the lnb and your dish that'd be great. I didn't understand anything you mentioned about the feed horn / scalar rings though.
