For organizations still utilizing IPX:
The transition from the PCB microstrip/stripline through the receptacle and into the coaxial cable is a point of high impedance discontinuity. The IPX566 design utilizes a specific "hermaphroditic" contact style (two vertical spring fingers) that ensures a stable four-point contact with the plug, significantly reducing impedance mismatch compared to older U.FL styles. ipx566 link
