This works with the Old DishTV receiver with built-in modulator, why not with Joey with a 3rd party modulator ? . . . I have a relative with the older DishTV receiver with the built in modulator for a second TV. The installer fed the modulated output from the receiver back to the 1 to 8 splitter in the basement on the same coax leading to the Dish Receiver. They can watch the 2nd channel from Dish from anywhere in the house.
Are there frequency overlap issues, needing a special modulator ? Are there bi-directional splitter issues . . The one big 1 to 8 splitter at my relatives house lets the modulated signal come in on port 3 and go out on the other 7 ports to all other TVs. (from the old Dish receiver). The incoming Dish signal and the modulated signal all seem to happily coexist on the same wires.
If it doen't work Im screwed because we have more than 3 must-have TV's.
