[QUOTE="rolfw, post: 16848, member: 175057"] Adjusting the LNB skew could certainly improve signal quality, as given an unobstructed line of sight, those signal strengths should give uninterupted viewing in good weather. The design of these LNbs is such that if the skew is not right, the perfomance of the offset LNB will be much worse than the prime focus LNB and this may be your problem. Adjusting the Skew will lift the Astra half and possibly address the dish at a better angle. I would also try tweaking the dish, I would have thought that you should get excellent strength and quality with your dish size. If you can get a portable TV out to the dish, then before loosening any of the brackets, hold both sides of the dish and tip it fractionally in one direction, if the signal increases move it that way. Tighten up and do the same again and then in the vertical plain. PS. There has also been some discussion as to whether the monobloc LNBs work well with dish sizes over 80cm, I've seen some pretty impressive trig workings explaining both sides of the argument, but am still undecided.
