well heres some real numbers Approximate number of people
unable to receive any channels after digital conversion 5.6 mil

They may be numbers, but they are not real. Where did the numbers come
from, and by what method were they obtained?

population maps compared to TV coverage maps?

That wouldn't give even an approximately correct answer. How can you
tell on that map, which houses have cable, dish or antenna in use?

data from cable/dish companies?
by percentage of cable penetration by zipcode,referenced to total
households.Few households are totally without TVs these days.

Then there are those who don't watch TV at all.

well,those don't count,in any case.

Add to that, the fact that the broadcasters aren't even exactly sure
where the precise perimeter of their coverage will be until they go
live and then do a lot of testing.

Which they HAVE been doing;the broadcasters aren't going to begin DTV on
Feb.17 without having thoroughly tested their DTV setup in
advance.Broadcasters have been simulcasting analog and DTV.

Computer simulations can do very well in regard to predicting coverage
areas,BTW. Broadcasters know their antenna lobe patterns,they map them so
they can orient to optimize coverage for their intended viewing area.

The real number of people who have TV reception capability over the
air may INCREASE after the switchover. For every Hallerb, there may be
20,000 people who see BETTER reception.

Doubtful,as DTV coverage areas are all SMALLER than the older analog.
Fringe areas will be hard hit.(until each station installs repeaters after
losing ratings points and being hit in their advertising revenue.)

Hallerb may ultimately end up with better reception. there is NO ONE
who can tell you for certain at this point.

one thing IS certain;I can't get WESH-TV Ch.2 on DTV,and that's the channel
the Super Bowl is on tomorrow. :-(

tried relocating the antenna to a different part of the apartment,no joy.
Ch.2 DTV is still on VHF...all the UHF channels come in.

so,it's back to analog,which I CAN receive.
