Is this because these are professional units? I found some "free

You can find 'software MPEG2 encoders' pretty cheap but none of them
will do real time MPEG encoding that will even begin to approach the
speed necessary to do a live newscast much less a basketball game.
They are also 'FCC - Illegal' to operate wirelessly into
an antenna in the commercial broadcast bands.
Well, you know, if nothing else, they could certainly fit into a
category of super low power TVBDs. You can buy boxes that generate
NTSC, over cables anyway, and you can certainly buy radios that
transmit wireless analog on the FM band. Seems odd that you can't do
the same with ATSC?
What would make their wireless dongle, capable of 480 Mb/s, so
consumer-friendly cheap?

With all the current fuss about interference in over the air ATSC
reception and white space issues, the FCC doesn't want a bunch of
consumer ATSC transmitters creating more havoc.
So far as I know, the ATSC 8VSB equipment is both outrageously
expensive and illegal to operate in the broadcast bands without a
license.
To be useful at home it would have to operate in the broadcast bands
because that's what the tuner in your HDTV set is capable of tuning.
When something changes radically and these little 8VSB ATSC modulator
things become readily available you will be well aware of it because
there will be ads, commercials, people sending notes to this forum
about it and most importantly you'll be able to buy one for $99 at
Sears, WalMart, K MART, Radio Shack and Best Buy.
Someday even complete, outmoded exciters at hamfests and on eBay! #;^)
