Hi My in-laws have bought a new house which doesn't have a TV aerial, only a Sky dish with a dual LNB and shotgun cable going in 2 rooms (1 downstairs, 1 up). I note that Freesat from Sky is subject to a £259 (!!) charge. Does the Freesast service work via Sky dishes?? If so, is the Humax HB1100-s easy to set up and use?
