RP-SMA Plug to RP-TNC Jack RF Adapter (CH-RAP-RTJ) is a 50 ohm between-series adapter that converts an RP-SMA plug interface to an RP-TNC jack interface.
This adapter connects RP-SMA-equipped cables or devices to RP-TNC-equipped equipment, or vice versa. Both sides use reverse polarity contacts — the RP-SMA plug has a female centre contact and male outer coupling; the RP-TNC jack has a male centre pin and female outer coupling. Reverse polarity swaps the centre contact only, not the outer shell. This adapter is commonly used in WiFi and wireless networking where equipment from different manufacturers may use different RP connector series. Confirm the plug/jack format and polarity at both ends before ordering.
