Product detailed description
The gold-plated RP-SMA – SMA coaxial adapter is used to connect an antenna with an SMA connector to a Wi-Fi router with RP-SMA, or conversely, a Wi-Fi antenna to a module or device with SMA. It is suitable, for example, for connecting a LoRa or Meshtastic antenna to a device with a Wi-Fi connector, or for using a Wi-Fi antenna with an ESP32 module, LoRa, or measuring instrument. The adapter is of measurement grade with a guaranteed VSWR max. 1.20:1 and insertion loss max. 0.20 dB up to 18 GHz, ensuring no significant losses in the signal path.
Difference between SMA and RP-SMA:
- SMA male: internal thread (coupling nut) and centre pin – common in LoRa antennas, modules, and measuring equipment.
- RP-SMA male: internal thread, but with a socket instead of a pin – typical for Wi-Fi antennas and routers.
- For females, it is the opposite: SMA female has a socket, RP-SMA female has a pin. Both types can be screwed together, but the centre conductor will not connect – which is why this adapter is required.
