The U.FL connector for all of those mini-pci cards and PC cards that have gone to this new connector. The U.FL (Hirose / IPAX) connector on RG178 cable (other cable sizes available on request as special order).
Special note with the U.FL connector - these are NOT a duty rated connector. Once it is connected it is strongly suggested to leave it connected. Due to its size and design its use in a plug and unplug situation will be very limited and will not be covered under warranty.
