25cm IPEX 1 to RP-SMA Female Connector Cable RG178

This cable is compatible with any wireless module or board featuring a female IPEX (MHF) socket, commonly found on ESP32, ESP8266, nRF52 BLE, and many 4G/GNSS modules. The RP-SMA female end connects to standard external antennas with RP-SMA male connectors, typical for Wi-Fi routers and boosters. Ensure your device's connector is the IPEX 1 (MHF) generation for a proper fit.

The RG178 coaxial cable is rated for frequencies up to 6 GHz, making it suitable for 2.4 GHz and 5 GHz Wi-Fi, Bluetooth 5.x, and 4G LTE bands. While it supports high-frequency signals, insertion loss increases with length and frequency. For optimal performance in 5 GHz or high-power applications, ensure the cable is kept as short as possible and avoid sharp bends to maintain impedance matching and minimize signal attenuation.

First, securely click the IPEX connector onto your module's port, ensuring it is fully seated. Route the flexible RG178 cable away from noise sources like power supplies or digital buses. Use cable ties or adhesive clips to avoid strain on the connector joints. Finally, screw the RP-SMA female end onto your antenna's male connector hand-tight. Avoid bending the cable immediately at the connector, as this can damage the internal solder joint over time.
