Hi Kromkamp. My condo is facing almost exactly southwest (I know this because my Directv dish is pointing straight out the window with another building about 50ft in front of mine). I am not facing the lake (Buffalo). The antenna is simply sitting on the floor and my signal strength is about 82. If you know the area, I live near Dundas and Hurontario (Hwy 10) just south of Square One.
Additionally, when I first picked up the Silver Sensor antenna from The Next Big Thing, I was also planning to get the CN Tower signal, which I only managed twice with a perfect HDTV picture. The rest of the time it failed. I think it is because they change the type of signal broadcast as a part of their tests. Even now it just kinda blinks with intermittent picture and fine sound. I almost sold the Silver Sensor too but it's a good thing I kept it. The bowtie I had didn't work well.
The signal from Buffalo is perfect now. No problems! GOOD LUCK!
