This is for commoman. I currently have a satellite tv system with dish network. I have 4 coaxial cables coming off of the dish to 4 different tv's. We recently purchased an additional high def tv. I am going to get a new high def box from dish network. But I would like to split the signal coming off of one or two of the existing coax's coming off of the dish so I can still hook up more tv's utilizing the same 4 receiver system. Is it possible to split the signal coming off of the dish so I can use one output for two tv's?
