I have a long range vhf/uhf antenna, being from just north of toronto, I first pointed the antenna line of sight to the CN Tower and Grand Island NY. When I scanned the channels I was only able to receive some Toronto Channels and No buffalo channels. So What I did was rotate the antenna away from the CN Tower and pointed the antenna towards just east of Buffalo near the WGRZ tower. There I was able to receive all the local channels because of the high powerful strenght of the CN Tower and having a long range antenna I was able to recieve to my astonishment all the Buffalo Channels, Including WIVB which I hear is the hardest buffalo channel to pick up and I am over 95 Miles from the transmitter.
