Dish just replaced my 921 with a 722 and at the same time replaced the dish 500 and DPP LNB with a Dish 1000.2 and DPP+ lnb's. My problem is signal strength on the receive alignment meter. With the 500 and DPP signal strength on the 921 and 510 were in the high 90's now signal strength on the 722 and 510 are in the low to mid 20's with a note on the screen saying that the calibration is different. I also notice that rain fade appears (note appears) to be worse with the DPP+ lnb's. Is this normal or did I get a bad install?
