[lime-users] modifying a router to add antenna

Has anyone modified a router that had non-removable antennas to add an attachment for a removable antenna? I imagine it would require: - acquire male RP-SMA connector. - open the router, cut a hole somewhere in the casing, and mount the male RP-SMA connector there. - disconnect the wire of a stock antenna and put a wire from that part of the board to the RP-SMA male. - close the router. Doing this, the router keeps its stock antenna(s), but one of them is disconnected. I guess there's a question about how much power the radio puts out, to know what sort of antenna will work... I don't yet know much about those calculations. ~ P
