Have just the new against the old LNB Inverto LNB (about 9 years old, manufacturer ??) exchanged. There are 3 different Reciver, connected with 2 different satellite cable qualities. The previous reception quality was not bad. Only one device (bad Baumarkt-cost satellite cable) the sound was always provided with a background noise. Had hoped that this can be improved with a new LNB. Had the reception qualities and the level recorded in all 3 Recivern / TV's before and after the change the LNB. The new LNB has brought measurable improvements. Reciver 1: quality from 76 to 78, the level of 74 to 87 !! Reciver 2: quality has remained at 98, the level of 73 on the 82nd Reciver 3: Qualtiät from 78 to 79, levels from 77 to 81st Subjectively, the picture quality appears much better. The Reciver / TV with poor sound has become subjectively better, although not 100%. Conclusion: Maybe I had in the past a bad LNB with which I, however, except for the bad sound at a Reciver / TV), was quite satisfied. This new LNB brings but in all respects a significant improvement !! Have the highest pleasure !!
