Canal Algerie on 12146 V on T5?

[Kanakanak]

I moved the LNB as far as I can from the dish (I also try to twist it a little bit) and this give me between 5 And 12 % more quality on each tp on IA5 , but only 0-1% quality on 11874 H now at least I have a picture of Canal Algerie but picture and sound often broked up because of the poor quality signal...

If you cannot get TP 11874, maybe a lower noise figure lnb can help.
