elevation
Using Google earth, I was able to determine my topographical elevation. My house sits at about 192 ft above see level. My house, being at about 27ft high, and the antenna adding about another 7ft, so it would place my antenna at about 226ft.
Norwood, NY, sits at around 330ft. I just do not know how high the WNPI broadcasting tower goes. So this means a lot of flat land between these two points, and a slight elevation in between could mess things up. There is a small plateau in between which goes up to about 291. So I just do not know if all this simply means that I'm doomed in ever receiving a clear HD signal from the US.
Otown47 comments seem to indicate that I'm simply wasting my time and money, so I just do not know where to go from here now.
Again last night I was able to receive the flashing HDTV signal off and on, with a weak signal followed by an intermittent strong signal. I was able to get this for both channels 23 and 38.
