I came to the conclusion after reading German forums about the polariser that it had not been setup in correctly, now seems to be okay also my dad as I've said is better at metal work has fashioned a better simple way to attach the full C band LNB to the LNB arm and now it's increased signal across the board, some by 10%. I've come to the conclusion any home made LNB C-Band collar won't work well so ordered one designed to go with a Gibertini dish from Germany we'll see how it goes..
