Took me 6 months to figure out my LNB was aimed at the wrong satellite cluster the whole time
I spent close to half a year trying to get a stable signal on C-band. Kept swapping cables, replacing splitters, even bought a new receiver. Turned out I had the dish pointed maybe 5 degrees off target. A neighbor with a spectrum analyzer spotted it in about 10 minutes. Anyone else burn months on something that simple?
