[QUOTE="PoloMint, post: 23909, member: 175235"] A 1.8m offset dish will receive all channels here in good and moderate weather. As for the footprint moving or shrinking (beyond its daily pattern) there is no clear answer, but there are many theories. If anyone could confirm or shoot them down it would be appreciated. It could be intentional, if the actual footprint is bigger than the one produced by Astra, they might decide to reduce output to save power/prolong life etc. It could be that it is just age/deterioration of components; the footprint might continue to shrink until it reaches its official smaller size. Other theories say that the size hasn’t changed at all, it has just moved. If the satellite was slightly drifting off course when it was brought back again the whole footprint might move slightly so people on the edge would notice a shift. Also the satellite filled up (more transponders used) around two years ago, power to transponders already in use might be reduced, or perhaps interference is caused by the newly used transponders that are close in frequency to ones already in use. As I said there seems to be little or no evidence to back these up, and there are probably other (perhaps more accurate) reasons also. [/QUOTE]
