Apparently ATSC modulators are very expensive.  QAM modulators on the
other hand might be possible to get.  Now they will almost certainly
take a video signal and modulate it, not a digital mpeg stream, although
perhaps there are some that will take the digital stream directly without
being decoded first.

For example this might work:

Except it looks very expensive.

Not sure anything consumer grade (and priced) exists.  There really
isn't any real demand for such thing.
