Depending on the model of the card, for me a D-link, the antenna does not fit. Also I found an improvement when the PC is out of the closed cabinet where it was. The Wifi waves then reached her best logic. So I wonder if we should not focus rather an antenna extension (extension cable), which allows you to place the antenna where you want it. In my case an antenna extender allows me to leave the furniture antenna where it is while leaving the PC there.
