That is misleading to the point of being disingenuous, John.
The UK and Italy, each of which is the size of one small state in the US,
deploy 2000 towers each to cover their population. France uses 3000 towers. In
the US, we have a total to about 6000, counting the big sticks and the low
powered translators. That is a difference you seem to ignore. And not just
that, but it only takes a few dozen transmitters to cover the majority of the
population here, as we discovered during the debate about how many O&Os exist
today.
Also, I'll remind you that this miniscule power you're talking about is
translating into very tenuous indoor reception in those Euro countries. Even at
close range.

Sinclair found a 2 dB difference in favor of ATSC, but they also couched that
with an acknowledgment of how bad those 1st gen receivers were.
