Yesterdays progress after work:
Went to the camper put out the bedroom slide and forgot to shut the control cabinet door, went to walk up the step and BAM! Yep the thickness of the cabinet door on top of my head split wide open. Good times, I highly recommend it!
Anyways, after I get myself to stop bleeding I man up and finish my project. Set up the dish and and try to put the receiver in the room. Still no dice. I did confirm that the diplexer is in the plate the correct way. Next step is I think I am going to purchase a swm 4 way splitter and run it exactly the same way as my house when we have to move. I will not be using antenna and if I do I can change it underneath real quick. If I come up with an other ideas I will be sure to make notes here for anyone in the future.
If someone wanted to try it I did see that a SWM 8 has place for cable and antenna input. The SWM 8 has a built in diplexer, this would mean that you would have to remove the diplexer at the wall plates for each TV. If I have time I will purchase one and see if it works.
