A:AnswerYes, if the armoire doesn't have in it any electronic devices or TVs or any metallic shields inside. If there is only plain wood of the armoire (and a few screws) between the antenna and the windows it should be ok.
A:AnswerUnlikely, unless you are extremely close to the source of the signal, and you will want to be able to move it around a lot if there is more than one source.
A:AnswerI have mine mounted near a window on the inside so snow and rain have no affect on the reception. My streaming no service offers a dvr program if I need it.
A:AnswerThe TV would probably interfere with the signal. I placed one behind a TV and lost about haft of the channels. Place it on wall or works best on a window.
A:AnswerKeep trying different places for your antenna. The higher it is, the better. Try putting it up in the attic or near a window. Keep it away from metallic objects as well.
A:AnswerI threw mine away, also. Basically, connect to RF_IN jack on TV. Plug in power adapter, mount antenna, do a channel scan on digital channels, rotate antenna, do another channel scan, move to a window position, do another channel scan any time you move antenna and see which is best position.
A:AnswerProbably not anywhere but the window. I have a house with aluminum siding, and the only place the antenna would pick up any channels at all was in the window. Still, all you can do is try it out in different locations and see what it receives.
