A:AnswerI think it really depends on how many stations you have in your area. It would help if you could mount it high up maybe in the attic to help bring it in. I was not satisfied with it in my house.
A:AnswerIt comes with 3 ways to mount. 1) 2x small pins with mini globe ends to push into drywall thru small holes into the top corners (hanging). 2) sticky foam pads to stick to a window. Or 3) a metal bracket with two small plastic vertical legs that slide into the bracket. The thin rectangular frame then slides into these legs to stand it vertically on a horizontal surface.
A:AnswerOurs is on a wall facing a window, but I'm not sure that makes any difference. Just because glass is transparent to light doesn't mean it's transparent to TV signals. That's a question for an electrical engineer.
A:AnswerWhile I have not tested it outside the country, I imagine it works much like any other antenna. My old Panasonic TV was giving me the option to search for both analog and digital channels so I imagine that yes, it does work anywhere.
A:AnswerYes. The limitation is the cable length which I believe is 16 feet. In my kitchen I was 18 feet from the window, so I added a 3 foot extension.
