Just to clarify things: 'Freeview' is actually transmitted by two separate private sector transmission companies: Arqiva and NGW. The broadcasters pay these transmission companies for carriage of their services. Arqiva acquired the commercial broadcasters public networks when they were privatised years ago and NGW acquired the BBC's transmission networks when they were privatised years ago. Arqiva currently transmits the low-power DTT services of the commercial broadcasters and NGW currently transmits the low-power DTT BBC services. Arqiva has won the contract to build and operate the BBC's high power DTT network currently under construction and the contract for the commercial broadcasters is soon to be announced. Topologically all the services are transmitted from the same mast in each location, each company has its own buildings on the sites, and access to the masts is regulated. This means the coverage patterns are very similar as the frequencies are grouped and you only need one antenna. Very simple and very tidy. Its a key reason why DTT, apart from its working COFDM standard, and the portfolio of services which are free is such a runaway success. The things which make Freeview work are economies of scale and scope in both the supply and demand side: a) A regulated private sector transmission business with a meshed colocated network technology b) A strong free content lineup c) Works with existing aerials, no rotors thank you very much d)COFDM e)Multiple suppliers of IDTVs and STBs f)Clear consumer demand: its now a utility purchase.
