Hello again to this great team!!!

i have zgemma H7S(si2169d) and edision os mini(montage)

i have them in same motor same dish same cables with splitter 2 port ( if the one is on the other is off)

my question is:

in the same channel edision says 98% signal and Zgemma 79%

I can see tha Zgemma has lower signals.

Why is that?

Thank you very much!!

i forgot i have inverto black single ultra high gain lnb.

Sigh..... An STB is NOT a measuring device. You will always see differences when using different STB's. Even between STB's of same brand and type. Some tuners are simply more sensitive than others...

That's because people have to learn not to rely on nonsensical percentages to measure or compare the signal.
Change the snr to db in both receivers and then compare them!

Granted, but we don't have to generalize! It's all a matter of hardware and drivers. I once compared my OSmini's BCM73xx tuner to a promax analyzer and I was blown away at the accuracy! In any case snr in db is always better than percentages!
