I, too, get rain fade. However, even on a good clear day my best signal quality reading is in the mid-80's. Techcop is right IMHO. The problem with rain is the density. A dense light rain is worse than a big-drop hard rain because the signal has to penetrate a larger volume of water. Dense rain makes it like is trying to receive a signal under a sheet of water...there is significnt interference. The waves likely get around large dispersed drops. For us in the Pacific NW, we have two strikes against us: we have a long, low shot to the horizon and we have a long, dense rainy season. Oh yeah, make that three: We also have a lot of trees, something that is giving me fits these days (particularly now that my neighbor's deciduous ones are getting their leaves and I'm trying to shoot my dish through them!).
