While debugging a professionally installed system's OTA problem I noticed that the power inserter going to the DPP44 is installed after the diplexer, e.g. Dishes -> DPP44 -> Diplexer (add OTA) -> Inserter -> Receiver This seems at odds with the instructions. It's been working almost a year. Did I misunderstand? Should it not be: Dishes -> DPP44 -> Inserter -> Diplexer (add OTA) -> Receiver Should I change? How can it be working? I can call the installers, but I wanted a sanity check. Actually it's a 2 minute change, I can also just change it, but want to make sure I know what "right" is. PS. The problem I was having is they used a TERK antenna, and it just is a piece of crap.
