I currently have a 3-LNB oval dish and a 4x2 multiswitch. Sats A & B are connected to their respective inputs on both output sides of the multiswitch. Sat C only has 1 wire coming off it and it's combined with the Sat B wire using a simple splitter/combiner on the Out1 side of the multiswitch. I have coax running off both Out1 and Out2 and going under the house. Only 1 of them comes into the house (the other is left under the house) and connects to my STB. I assume that must be Out1 since I get signal off Sat C and it's only hooked up to Out1 on the multiswitch? I recently upgraded my old Sat520 box to an HR10-250 and only Tuner1 is hooked up of course. What I'd like to do is: Connect the 2nd tuner on the HR10-250, and Eventually put the old Sat520 on a 2nd TV in the den (currently only OTA) Do I need a different multiswitch? How do I get Sat C on both (well eventually all three) outputs? What parts do I need and how do I connect it all up properly? I'm happy to read up on the procedure myself if someone knows of a good link. Thanks in advance!
