I have a DirecTV 5LNB satelite dish, with 2 incoming feeds into a low voltage box in my house. One of these feeds is currently tied into another cable to feed my master bedroom, and the other cable feeds my bonus room. I have two other bedrooms that I would like to install receivers for, so that each can watch satelite independently. Is it possible to split the two incoming feeds before they feed the receivers in the master bedroom and bonus room, and be able to install independent receivers in the other two rooms?
