I got a 211 for the rv and hooked to a 500 dish it worked but not at home because 119 ? is to low in the sky. I have DirecTV and a portible dish with one LNB so I tried that at 62.5 it worked. Left home and used the 500, came home again and when I do the check switch it says I have nothing. Can the LNB just go bad or did it always say nothing connected even when it worked? I think it used to say CONN on port 1 but it says X now.
