in Portland, Oregon, where the analog and digital signals are coming
from
~2000' HAAT..

My experience here in Dallas is just the opposite -- very low powered
digital signals from a 1500' HAAT transmitter site come in perfectly at
my home 35 miles away, while analog signals at remotely similar power
levels are extremely snowy.

Tom,

The problem is, with digital, it's either there or it's not. There is no
fringe area. In Oregon, and other mountainous states, it's much different
than Texas, Oklahoma or Kansas, where it's mostly flat. Even within the city
of Portland, there are large numbers of places that are not line-of-sight,
even from antennas at 2000' HAAT.. and the digital signals are not there at
all in the shadows of any of the hills, nor are they available out on the
coast, whereas analog signals, although relatively poor, are..
