I live in Charleston, SC and we have had the 6th largest amount of rainfall since 1938 this June. Needless to say more rain fade than normal also. So my Dish is basically aimed South West, but most of our Broadcast Antenna's are to the North East. Seems like watching the radar after the major storm moves to the East the Signal comes back. So it looks like I could watch the locals most of the time when rain fade kicks in. I have a new dish, LNB, and signals in 90 - 100's range. I have HD, cinema connect kit and due to get an upgrade later this month. So any ideas on is it worth getting the AM21?? And is this a viable option to consider??
