Every time I use one of these switches I don't get any reception. If I connect the cable directly to the receiver I get reception from all transponders. So at the moment, depending on the channel I want to see, I'm switching cables back and forth. Usually I have to play with the switches itself to get some sort of signal. Like for some reason If I screw the cable in completely I get NO signal, If I leave the end of the cable slightly unscrewed I start seeing some signal and even then its very low somewhere in the 40 percent range. Also how can I check if I have a bad sw21 switch? In my case, 3 total. Some info... DISH 500 - Want to connect to 110 and 119 I have 2 single dual LNB (I believe that correct) Receivers: 301 and DVR 522 (currently have the 301 active) I also bought the DVR 522 thinking since it has 2 connections for satellite in the back I would eliminate this whole switch thing and connect them directly, but that just wasn't the case If there is another way to do this, I'm open for options. Other than calling Dish themselves.
