I currently have a 3 LNB dish with two wires running underground from a pole where the dish is mounted to a 4 output multi-switch feeding 4 tuners in my house. I would like to install a Slimline dish but not want to dig under my driveway again to run 2 additional lines. Will a SWM allow me to have only two inputs from the dish and 4 outputs to my current receivers so I dont have to add wires underground? Thanks in advance.
