I'm thinking about getting a Freeview decoder but don't understand why HD is only available via UHF, which may or may not be available at my location (the maps don't help, they just say maybe or maybe not).
Can anyone explain more about this to me? Why is HD available on Sky but not on satellite Freeview, and why are there no apparent plans to change this? Is it a matter of money, or available bandwidth, or something else?
