I think OTA tv is an inefficient use of spectrum. Judge Judy, Maury, ricki lake reruns?
Each 6mhz channel can host 3 separate streams so you have fox, NBC, abc, wb, upn, PBS, CBS.
Reduce to 4x6mhz for TV and you can get 12 channels which is about how many I get on antenna. They won't be hd but access to hd is not a constitutional right.
