According US FCC (Part 15.203) regulations, wireless radio equipment with removable antenna must not have a standardized interface. This to avoid the connection of antenna equipment which is not WLAN approved.
An established solution is the so called reverse polarity connectors. That means, the male connector is fitted with female center contact and insulator, whereas the female side is fitted with male center contact and insulator. For identification of reverse connectors the letter R (for reverse) is used in the type description.
