As long as it complies with Part 15, an unlicensed low-power ATSC transmitter
should be no less legal than an unlicensed low-power analog-TV transmitter, FM
transmitter, etc.
Computers and video-game systems used to provide RF output all the time to hook
into TVs that only had RF input; these are basically analog TV transmitters
with just enough output power to work over a wired connection. With a bit more
power, you can go wireless as long as it doesn't interfere with someone else's
TV reception.
