This USB antenna I ordered for a trade fair in which we wanted to show a wireless meter reading. If you want to show something with wireless data transmission at a trade show, then it must have an antenna! Everyone knows that. The antenna actually used was in the demo is not visible (installed in the housing). Acquired antenna has served its purpose well. Thank you to the manufacturers for the development of such a space-saving solution.
By the way: The antenna would have been to use as a wireless adapter. The driver could be installed under Windows 7 Professional and easily use the device as a native network adapter.
