I just installed a SWM LNB for my new RV and a power inserter. My question: When I plug my RV into an external power supply voltage will be sent to the power inserter. Is there a problem if the RG6 cable to the dish is not connected? I think I remember something from long ago that indicated there was a certain sequence when installing the SWM, so no damage was done to the various components. I purchased a SL3 with SWM and a 29v power inserter from Solid signal.
