But there are many rebuttals to this. One is that the earlier COFDM receivers were actually better than the newest Freeview receivers, the difference being the tuner itself. Another is that COFDM was *specifically* designed for these conditions. Where the signal level is adequate, you were testing it in exactly its natural environment. It would have been interesting to compare it with 4th and 5th gen ATSC receivers in that same environment, but such a test does not constitute the sum total of all comparision tests one would want to see. Unless US broadcasters make an effort to provide a good network of translators throughout the country, in the US we seem to have much bigger areas to cover with only one tower. Another is that this doesn't contradict the simple fact that professional outdoor antenna installations are the norm in Europe, for those wanting to receive all OTA stations in their market. This is largely due to the low power transmitted from stations and translators, no doubt, and also because apartment dwelling in large urban areas is also the norm. So apartment antenna systems or individual antennas on the roof of these buildings is a very common sight, at least in OTA countries.
