Hello,
Im looking to upgrade my LNB to see if I can further improve the signal and picture quality. I understand most of this will be dependant on the size of dish and alignment.

My existing LNB is a single standard universal LNB, I just wanted to change it for a higher quality one to make further improvements and want to know what type and spec I should go for.

I have a single tuner motorised system with 90cm TRIAX dish.

And if some once can advise on the correct procedure of changing an LNB ,dose it in volve a setup on MY et8500 Linux receiver or do I just swap it over?

Is there an LNB Scew required and how to I do this?
