New member, so be kind. I have monitored the AVS Forum for two years. I have been able to aquire the info I need by being passive - there are plenty of experts and by the time a thread runs its course I have little to add. But, this thread has finally convinced me to join.
TV in Bangor is bleak, but its not the fault of the local owners (CBS, FOX, ABC, NBC is owned by Gannett), the population is too small to support the infastructure needed to provide HDTV.
The NBC HD is great I get a signal strength in the 90s on my DTC 100, PBS is OK in the 60s. From my location I'm in between the two so I have to move my antenna (attic installed modified RS double bowtie). I don't bother because rarely there is anything on PBS to watch. In fact I don't watch NBC that much, local weather and Golf. The CBS and ABC HD are upconverts, I can't receive either. I just ordered a new antenna to see if makes a difference.
ExpressVU looks tempting but additional equipment costs so far has deterred me. BTW I have talked with the ABC and CBS engineers. ABC low power till ordered to go higher, CBS upconvert, the tower is located 20 miles away and no plans to invest for the equipment for true HD. My .02.
