What is a Reverse Polarized Connector?

A Reverse Polarized Coaxial Connector alters a standard connector interface by utilizing a male pin center conductor in a female threaded coupling mechanism and a female basket center conductor in a male threaded coupling nut mechanism. This prevents mating with a standard non-polarized connector. This type of connector is required by FCC part 15.203 rules for spread spectrum wireless devices. Common Reverse Polarized interfaces are RP-SMA and RP-TNC.
