The DISHPro switches really aren't that complex. The output from a DISHPro LNBF is actually splittable. The only reason for a switch is to switch between satellites. The old method was a multiswitch. It actually had to both switch between satellites, and switch between polarities. The main advantages to the new system are ease of installation, and better install reliability (no more need to worry about the voltage not getting through). So it offers no real advantage to an existing install, but is an installer's or a new satellite owner's dream
