SMA to uFL (Female) RF Adapter Cable This SMA to uFL RF Adapter Cable is super handy for anyone doing RF work. Often times, small electronics save space by having a pick-and-placeable u.FL connector (also called uFL, IPEX, IPAX, IPX, MHF, and AM). But most antennas have SMA or RP-SMA connectors on them. This little cable will bridge the two! Most WiFi devices/routers that have a connector use RP-SMA. Check the antenna you want to connect, and the close up image above to verify if you need RP-SMA or SMA as they are not compatible!
