Advertisements I have been searching all day and cannot seem to find and exact answer to this. I have round dual LNB dish with a single coax wire running from it. I purchased a splitter and a non-powered multiswitch to handle the two lines in. On the splitter I took two lines from there and hooked them to each of the LNB connections on the multiswitch. I test and setup all works well. I do get some errors in guided setup about not being able to access all the channels but it lets me finish the setup. Ok, now I am able to use both tuners, but from time to time I lose signal on either of the tuners. I noticed this when one is in use for recording. If I run a system test I am showing the signal is lost on one input. I think run a signal test and it shows both signals are in the 80 - 90 range. I then go back and both inputs are working again. If seems like everytime I get the Searching for Sat. signal, all I have to do is test the signal strength and all starts working again. I have also noticed that when I lose signal, it does not affect all the changels, just a select few. I have swapped wires around and still same problem which switches to either tuner. Can anyone tell me if I have hooked it up correctly or is there something else I need to do? Thanks in advance!
