Regards! Friend, when you have that arrangement of connections in a satellite dish, two coaxial cables coming down from the antenna and to a box (In that box what there is is a Spliter or signal splitter), what you have is a shared connection of an antenna to Several decoders. An antenna can have an LNB or receiver at the tip of one or two connectors called Double LND and you can connect one or two decoders at a time. Adding a special spliter or splitter for that matter (this is what you call the box or is inside that box), multiple receivers can be connected to a single antenna, depending on the type of spliter or multiswitch, its name itself can be connected 4, 8 or 16 decoders simultaneously to a single antenna and even more, with special amplified multiswitch, for a whole condominium. In addition to that you can add the cable or terrestrial aerial antenna signal for all decos also in other signal inputs that they have. In conclusion, if you remove the antenna or eliminate that arrangement of connections, you are going to leave all those who are connected without satellite signal, and if they have added the cable or terrestrial antenna signal, too. I suggest you study who are connected and if they have this system active, you could choose to move the antenna and the multiswitch box. I hope it serves you and I have not extended too much!
