Query: It works

I had a Terk indoor/outdoor antenna installed previously. It pulled in most of the available HD channels, but not all of them. I put it in my attic and got the same performance. I set this one up in my living room and it pulls in all of them. And the closer it is to a window the better it works. It's an eye soar sitting here though. I want to see how it works in the attic, but haven't gotten around to getting up there in the summer heat. Since it pulls in signals through windows I don't know if it will work well behind a roof. It's too unsightly in the living room, so if it doesn't work in a hidden spot, I won't continue to use it.
