I have a Dish Duo setup. I hooked up diplexers as described in the forum and it worked for about 5 minutes, then I got total loss of signal on my satellite. I then removed the diplexers and hooked it up as it originally had been installed, but I still have a loss of signal. The other receiver still works fine so I know I am still getting the signal from the satellite. Could the diplexers cause something to short out?
