This is a basic RPSMA (Reverse Polarity Sub-Miniature A) male to female connector cable. Each cable is 25cm (9.8") long and has a 50Ω impedance that can handle frequencies up to 17 GHz. The RPSMA connectors at each end are small enough for most consumer WiFi and other RF applications and they use a threaded housing to create strong mechanical connections.
These work well for mounting an antenna to the outside of an enclosure, while keeping the electronics neatly inside.
