I live only a few miles from Crystal Palace the main TV transmitter for London, well within the M25 and I cant receive analogue channel 5 let alone digital! We have a local repeater but that does not have 5 or digital. As I am amateur radio enthusiast I can use my 70cm beam for television but not everyone would like a large (12 ft long)steerable aerial array on the roof! Too many glaciated valleys round here. And it not even quiet and peacefull round here on the A22! but we do have gas and cable TV.
