The RP-SMA connector (Reverse Polarity SMA) is a variant of the standard SMA connector that has a reverse center pin arrangement. This connector is designed to prevent accidental or incorrect antenna swapping between devices with different polarities. RP-SMA connectors are often used in home and commercial WiFi devices such as routers and antennas where compatibility with specific types of devices is required. Their design ensures a secure and stable connection while maintaining low signal loss.
