I got this antenna with the tower I got 2 months back. It's good if you're close enough. For me, it might work with the Toronto stations, but might be tough to pick up the distant South Buffalo channels like 2, 4, 7, and 49.
The concept and design is good though! :)
And I'm in Mississauga, you might have better luck, though I would reocmmend outdoor installation with a height that clears any nearby obstructions like your roof and trees. The enscarpment if you're on top might also be an advantage!
