Thinking about coming back to DirecTV after a year or two with cable. Previously, I had a non swim install (two HR20s). While an installer was next door, I asked him a few tech questions about coming back and I want to run what he recommended by the forum here. I have two TVs (one used all the time, one seldom); four coaxes run from the dish from the previous install with two coaxes to each room. I want a Genie in the den and a Genie mini in the bedroom. With that, the installer recommended using a SWiM splitter at the side of the house (replacing the grounding block). One leg goes to the Den, one leg goes to the bedroom. My questions are: #1 - Can a SWiM splitter be grounded enough to replace a grounding block? #2 - Can a SWiM splitter be exposed to the elements outside? #3 - Can a SWiM splitter be placed in the middle of a coax run or does it need to be at the receiver end? #4 - Does it make since to use a 1x2 SWiM splitter instead of a SWim switch if you only need two legs? Thanks in advance..
