Advertisements Hi. I live in a apt-building. From the dish (dual LNB) two coax go to a multi-switch 2 x 8. I had the normal directv receiver before TIVO that only needed one coax from the multi-switch, but now I got the TIVO receiver that needs 2 inputs to the new receiver. The problem I have is the tube (goes under the floor) where I pass the coax from the multi-switch has no room for two cables. Is there a way to duplicate the signal from the current coax connected to the multi-switch in order to generate the 2 inputs the receiver needs?
