Guys, sorry for what i am going to state now.... There are no huge difference between LNBs (IBU, GI, Octagon, Quad, Single, Twin, black, white, pink....) If they cost more or less same than they perform also more ore less same. Only one exception- Invacom, this one costs much more than cheap ones but performs also same
And it is actually not easy to make fair test, because it is very hard to place LNBs under test at exactly the same position. And any micro-movement of LNB gives different results. Some LNBs can perform better on lower frequencies and some do better on higher frequencies. Moreover, it is possible that A-LNB will perform better on A-antenna, but B-LNB will do better on B-antenna, when you switch LNBs, then may perform different again. All the tests are also weather dependent. Sometimes satellite signals are not equally strong over time, and if you tested A-LNB at 16:00, than same LNB on same antenna at 17:00 can bring completely different results. Another issue- same LNBs are different! If you have 100 same LNBs, lets say Black Ultras, than from that hundred you will not be able to find 2 LNBs giving exactly same results on all antennas in all weather conditions, on all frequencies, at the same time. I do not know, maybe performance also depends on receiver used for tests. Perhaps, if we have 100 OCTAGONs than some of them can perform better than some of the IBUs.
Therefore, before we say that IBU is better than OCTAGON, we should say little bit more about another actors (antenna, receiver, weather, time of the day, your personal mood, which satellite, which frequencies, outside temperature... ).
I know, what I say sounds maybe stupid, but those are my thoughts of today.
IMHO, better LNB today is IBU, I just feel it. Sometimes not easy to prove.
I just made small test on 5*W- scanned all frequencies by IBU and fixed results and than did the same with Octagon Twin and also took results. Placed data in spreadsheet. And spreadsheet shows IBU as a winner.
Used Fibo120 and DM8000.
