Well, my linear LNB wore out after a faithful five years. I don't have a bad thing to say but I do like these ultra-miniature LNBs from Glorystar a.k.a. SatelliteAV. Five years seems a reasonable lifetime for this sort of thing. The circular LNBs also met a similar fate. It could be my mounting and the fact that I sometimes clean it with a garden hose, heheh.
