If we are talking Freeview we are on the fringes of signal areas and are one of those parts of the country that will NOT be guaranteed a picture come the big change over ~ at least according to the Government web site dealing with the matter. We are lucky, so they tell me, to get any Freeview reception. Cross the street and they cannot receive it at all. Mountain in the way. Radio signals bounce up but do not come down again apparently. They do undulate but the slope is too much for that effect to work.
