Hi,
I have FusionHDTV5 Express tv tuner and channel master 4228 antenna. I can only get Canadian channels and nothing from Buffalo when I scan for channels. I live on the 20th floor and have clear view of lake ontartio and the distance from Buffalo station is ~42 miles, considering all these I should be able to get those channels from Buffalo. I have installed the latest version of Fusion HDTV too but nothing is helping to get anything but Canadian channels. Can anyone suggest what might be the problem herE?

First guess, assuming you are looking SE towards the Boston Hills is signal overload from the CN tower and 1st Canada Place. In the Mean time try these forums;

PS; welcome to the forums.

Thanks for the reply, videobruce. The antenna is actually facing directly South.

Where is the CN tower in this?

I did not quite understand what you asked? If you are asking about the direction of CN Tower from my place, then its SW.

Correct.
Swing over to the Buffalo thread.
