So the wife and I decided that we wanted to get rid of the 311 in the living room and push TV2 to both the upstairs bedroom TV and the living room TV. Problem is, the connection for my upstairs bedroom is outside at the old CATV entry plant and this necessitated putting the 2nd diplexer outside near the dish. I've attached a rough diagram as to how everything's laid out. I can also mention that there's a 4-way splitter in the basement that fed the other 4 jacks in the house prior to the Dish install that I was planning on using to feed the living room until I realized where the VHF/UHF splitout was. So, questions: would it be at all possible to add another diplexer in the middle to pop the signal to the living room without disrupting the signal itself, or is there some other piece of hardware I'll need? I would assume the answer to the first question is no because logically, I'll be 'removing' the signal from the line via the diplexer and thus couldn't send it upstream. Help!
