A coworker was asking about these (example) for use in his house as opposed to a car, thinking that maybe he could put it on his kitchen window and be able to get better reception. (My impression is that he gets reception but often gets static). I’m not even sure how something like this can help much without external power, I guess it just helps the signal get through the window.
So, for $25.00 is this a good product? Does anybody use one of these?
