[QUOTE="RimaNTSS, post: 885358, member: 312276"] I've measured 4,8*E spectrum of frequencies and situation is about the same: IBU attached to original Fibo feedhorn showed better results than Inverto Multiconnect (IM) Quad on T90. At very high frequencies IM outperformed IBU. Then I drunk some whisky and started to think maybe something wrong elsewhere not in Fibo! Basically I measured all signals with one receiver, but with different tuners. GB-Quad has A and B tuners. Tuner A, via some cascaded Diseqcs is connected to T90 dish, and Tuner B via positioner direcely to Fibo's LNB. So, I've measured everything with different tuners, and maybe one of them has some problem! That could be the reason! Will check this theory tomorrow. [/QUOTE]
