I have a legacy dish 500 set up with legacy LNB's, and another legacy dish at 65 deg. All switches are located outside, I do not know what they are. I have 2 satellite cables running to my basement, where I then have the connections to my receivers. I currently feed an 811 receiver in the living room, and a DishPlayer 7200 in the bedroom. I also have an old model 5000 receiver in a office, that I would like to feed by splitting the signal before the DishPlayer. I have tried a standard cable splitter, but this did not work. Could somebody tell me what I need to split this signal?
