Somewhat new to satellite but have been reading up on it a bunch. I have the general idea of how splitters, separators, and diplexers work. I'm trying to add a 2nd receiver to one of my upstairs bedrooms. Currently we have a ViP 722k Dual Tuner DVR in our family room. The output is feeding 3 of the upstairs bedrooms. We also have cable internet going into 1 room upstairs. I'm am wanting to add another receiver upstairs so we can watch different television on 3 different TV's. There is one line that comes from the outside carrying the satellite and the cable with teh use of diplexers. I'm trying to see if there is any way to add another receiver without having to get up on the room as I do not have a ladder that is that tall. I have attached a picture of our current setup (sorry it's not the best drawing). Thanks for the help!
