Have one on mine, should work just fine on your 50 feet. Mine does great in my house and it is about 45 feet from where I normally keep it. Have used it in stores and church and never lost the signal. Seams to have trouble reacquiring it again after it loess the signal though. I have gone over 5 miles (the absolute longest) from my house and it was still communicating. But once the signal is lost have had to be as close as my own driveway before it found it again. Sometimes farther away, but no closer then my own block.
