Sam, do you see the frequency sell off, new ATSC 3.0 etc helping, hurting or having no real impact in receiving an OTA signal.
I ask because if a few present channels go to a SUB channel on another existing tower to share that frequency, depending what the move is I could be without several Networks or some of the present channels I get because I don't get those towers now.
My guess is some people will be helped and some will be hurt. As I understand it, ATSC 3.0 will give locals the option of a vertical polarity transmission path (in addition to the horizontal pole in use now). That is supposed to at least help inside buildings (so I'm told). I'm not sure how/if it helps with distance yet. I seem to remember something about power output being helped, but again that might be limited by the FCC.
As far as the frequency sell off, you're basically looking at stations broadcasting at a lower frequency. That might mean someone on channel (real) 36 now, may end up on 22, or even on a high V. I know (from reading here) some people have problems receiving VHF, so again, will help some and hurt some.
The questions are though...
1) How much $$ will the wireless companies come up with in order to pay for the frequency sell off? In the reverse auction, broadcaster said they'd move for $86B. "Experts" had estimated the cost at $35B. Will wireless companies be willing to come up with another $50B to gain access to more spectrum? Will there be less spectrum sold off?
2) Will broadcasters be reimbursed to update to 3.0?
3) Will there be some way to broadcast 3.0 and 1.0 simultaneously and in a cost effective way?
FWIW, there is currently an ATSC 3.0 broadcast signal from WRAL. Of course, there are no consumer tuners to allow anyone to watch the signal.
