So there's no way that LOS is possible, unless I misunderstand what
LOS means. I don't know why others have such a big problem, so I
have to assume it is not due to the propagation path, but more to
front end overload, IM3 distortion, or other such effects, that
decent receiver design would solve.
Las Vegas is a valley too, with a whole bunch of multipath generators
in the middle.
It is important to remember that reliable mobile DTV was demonstrated
in Las Vegas in 2000, using a standard for which ease of reception
was an important consideration. At the time, the receiver was a thick
tablet that had very limited battery life.
Here we are today with a tablet that has a 3 mpixel progressive
display and 9 hours of battery life, when using 3/4G radios that can
receive and play HD video in real time.
The fact that this would become possible, little more than a decade
after the ATSC standard was developed was well known in the early
'90s.
But this has NEVER been about technology. It has been, and continues
to be, about the ability to protect an oligopoly that controls the
distribution of TV content.
