Moved into a new house and not sure how to get terrestrial TV. Thinking the previous owners had Sky maybe? Tried traditional antenna aerial but the TV won’t tune any channels. There are satellite (?) ports in the wall, can I get TV through these? Do I just need a satellite cable? Or a Freesat box? Would be happy with terrestrial/Freeview channels. Photos show various outlets/ports in living room and the ports in back of Samsung TV. Sorry if this is super obvious, I’ve never had cable TV or Sky before.
