Me. I get perfect indoor ATSC reception from 50 miles away with a quad 
bowtie in
a window for one station, a 1 MW one on a modest (well sub-1000 foot) tower.
I get perfect ATSC reception from 68 miles away with an indoor 15 
element Yagi,
at about 500 kW and a 1300 foot tower, for a different station. 

Both stations are "frequently" gotten with a double bowtie antenna, 
indoors, but
most certainly are not "reliable". The difference between a double and
a quad bowtie is large, for some reason.

I suspect that perfect ATSC reception at 52 miles with an indoor (2nd 
floor)
antenna would be a commonplace in Kansas, where 2000 foot towers are common.

These are all UHF channels of course.
