Then your reading comprehension is lower than I
thought.
1. I used both NTSC and ATSC, to show that both end
up being very similar in this regard. Unless you
want to deploy synchronized SFNs, the only advantage
of DTT is use of on-channel repeaters vs translators
to fill small gaps.
2. I showed 7 national networks vs 6, because I
included WB. Had I used only 6, no UHF would have
been necessary.
You flunked the reading comprehension test.
