Been using the silver sensor off and on in Oakland. I was able to get WPXI, KDKA, and WQED from my 6th floor apartment on Forbes Ave (facing N-NW). Now, in my first floor apartment on Semple St (facing south) I don't get sh!t. That's life in the city, though. Damn Comcast taking their time...
I've heard success stories from guys in the suburbs, including places as far away as Cranberry, which mystifies me because that's getting out there, and some of these guys are getting WTAE-DT... I guess it's just some dumb luck sometimes. Ultimately, the Silver Sensor is a very solid indoor antenna and when not surrounded by walls, and when given a bit of elevation, can easily get you some pretty good signals. It's worth the small cost now that you can't get the Radio Shack double bowties anymore.
