There are a couple brands of 12V ATSC M/H receivers out there (check Amazon, eBay) for $100 - $200. (If you don't know, ATSC M/H is the new digital mobile TV format that works even while in motion).

 

Has anyone installed one yet? Any suggestions? There are now 3 or 4 stations in the Dallas area broadcasting in this new format, so I'm thinking about getting one. I'm sure the rest of the "normal" stations will be on there soon.
