[QUOTE="jeallen01, post: 987405, member: 176704"] Question: did the dish originally have just a single-output LNB fitted? If so, the additional weight of the replacement quad LB may just have caused the LNB arm to sag a little and thus slightly misaligned the LNB wrt the signal reflected back from the dish, especially if the original installation was not spot-on - certainly a known problem when a much heavier Octo LNB is fitted. Certainly rain fade was a known issue with Zone 1 LNB installations quite a few years ago, so that is why I installed first a 60cm elliptical (on 25-30m of WF100) at the end of the garden and now a Zone 2 dish much nearer on the conservatory roof. OTOH, as has been said, nowadays the signal is far stronger and even a slightly misaligned dish should get a decent signal almost all of the time. [/QUOTE]
