"Digital really knocked signal reception for six."
That's because most people had the cheapest aerials they could get away with. ISTR the Maplin catalogue used have a few pages specifically about the various transmitters around the country and which bands they used so you could select the correct aerial. I paid a little extra for an "all band" aerial 30 odd years ago and it's till working well with Freeview. Having said that, it's on the roof and we are in a good signal area.
