I understand the idea of this is to double the bandwidth, but
ignoring that, how much better would ATSC work if all the
transmitting antennas and receive antennas were circularly polarized?
It seems to me most of the problems with ATSC reception are caused by
pre and post echos confusing the receivers. How much would circular
polarization improve this problem?
And why hasn't this idea surfaced before? This seems to me a huge miss
for improving ATSC reception on everyone's part.

What they are trying to do is double the bandwidth so that they can
add an MPEG4 HD service on the same channel as the current SD service.
