I believe that the loop out feature works slightly different between the different makes and models. Some makes will send out the opposite polarity signals to the 2nd receiver when the 1st receiver is on, and will send out both polarities when the first receiver is turned off by the remote. Sometimes the 1st receiver will only send out the signals to the 2nd receiver from whatever sat it is tuned to when it's turned off. i.e if left on 91 it will only provide the 2nd receiver with 91 info. I think that sometimes depending on the different makes and models the 2nd receiver can control the switch and will switch between the different sats when the 1st receiver is turned off. I'm not sure if I'm totally correct in this assumption but I believe that different makes and models act differently and this is the cause for the confusion on how the loop out feature works.
