Except that the DTV converter box program included a VERY stringent set
of technical standards for the boxes. In order for a box to be approved
as eligible for the coupon, it has to meet standards for sensitivity and
selectivity that far exceed the performance of most of the OTA DTV
tuners currently on the market.
This is not going to be a repeat of the numb-as-hell UHF converter days.
NTIA's on the ball on this one. I can't wait to get my hands on one of
the new boxes in a month or two to do a shootout against my Accurian
converter box, which is only middlingly sensitive.
I'm not going to try to claim that someone in a signal-vacuum area like
Keene or Winchendon is going to get stellar results with rabbit ears all
of a sudden. In the long run, it may be up to broadcasters to extend
better service to these areas through the use of on-channel "single
frequency network" DTV booster systems, which are much more practical in
the digital realm than they would have been in analog.
I do know that as I go driving in rural areas at some distance from the
transmitter sites in western and central New York, it seems as though
almost every home now has a dish in front of it or on the roof. I
suspect that these days, penetration of direct-to-home satellite service
is running just about in inverse proportion to OTA signal strength.

WRGB is absolutely convinced that on digital, low-V will carry better
into the hollows and valleys of eastern NY, VT and MA than the Us will.
In terms of raw signal strength, they may well be right - it's certainly
true of their analog signal. The big unknown is how bad electrical
interference will be, and what effect e-skip might have on the channel 6
signal come summertime.
