I have an old Glorystar setup with GeoSat pro HDVR1200. Have used this off and on. When I started using it more frequently I noticed that the signal quality never gets above 50%. This means only reasonable reception on the best weather days. I tried if readjusting the dish and LNBP angle would get me any improvement, but it turns out I was already setup in the sweet spot. I am running out of ideas on what to do. Looked up LNBP information and read in product description of one particular type that "standard" LNBPs are only good for 5-7 years or so? Do I need to consider swapping out the LNPB?
