Description

This 20cm coaxial pigtail cable is engineered for seamless RF signal transfer in wireless communication systems. Utilizing 11mm RG178 coaxial cable with a 50-ohm impedance, it ensures minimal signal loss and VSWR, maintaining link integrity for sensitive IoT and networking hardware. The assembly bridges the compact IPEX 1 (MHF1) connector, common on embedded Wi-Fi/Bluetooth modules, to the standard RP-SMA Female port found on many external antennas.

Its flexible design allows for clean integration within tight enclosures of routers, development boards, or telemetry units, providing a critical extension path for optimal antenna placement. The robust construction of both connectors guarantees repeated mating cycles without degradation, making it a reliable component for prototyping and final product deployment across various frequency bands.

Key Features

  • Low-loss RG178 coaxial cable maintains signal integrity for 2.4GHz/5GHz Wi-Fi, Bluetooth, and cellular frequencies.
  • IPEX 1 (MHF1) male connector mates with internal antenna sockets on compact wireless modules.
  • RP-SMA Female connector interfaces with a wide range of external antennas for improved gain and range.
  • 50-ohm impedance matching minimizes reflections and ensures efficient power transfer.
  • Flexible and durable cable jacket allows for easy routing within device chassis.
  • Essential for relocating antennas to overcome RF shielding or for optimal polarization.

Applications

  • Extending internal antennas on ESP32, ESP8266, Raspberry Pi, or cellular development boards to external ports.
  • Connecting Wi-Fi routers or access points with internal IPEX sockets to high-gain external antennas.
  • Integrating Bluetooth/BLE modules into enclosures where external antenna placement is required for range.
  • Providing antenna connectivity for 4G LTE, NB-IoT, or LoRa modules in asset tracking and telemetry devices.
  • Prototyping and testing wireless systems where flexible antenna positioning is necessary.

Frequently Asked Questions

What devices is this IPEX to RP-SMA cable compatible with?

This cable is designed to connect any wireless module with an internal IPEX 1 (MHF1) socket to an antenna with an RP-SMA male connector. It is commonly used with ESP32, ESP8266, Raspberry Pi Wi-Fi/BT modules, cellular modems (4G/LTE), and many commercial routers that have a small IPEX port for an internal antenna. Ensure your device's connector matches the IPEX 1 type before purchase.

What is the impedance of the RG178 cable, and why does it matter?

The RG178 coaxial cable has a standard 50-ohm impedance, which is critical for RF applications. Impedance matching between the cable, connectors, and your wireless module/antenna minimizes signal reflections (high VSWR) and ensures maximum power transfer. Using a mismatched cable can significantly degrade signal strength, reduce range, and cause data errors in Wi-Fi, Bluetooth, or cellular communication links.

How do I properly install and route this antenna extension cable?

First, securely mate the IPEX 1 connector to your module's socket, applying gentle vertical pressure until it clicks. Route the flexible RG178 cable away from power lines or noisy digital circuits to avoid interference. Connect the RP-SMA female end to your external antenna's male connector and tighten by hand. Avoid sharp bends or kinks in the cable, and use strain relief if needed. The 20cm length offers flexibility for optimal antenna positioning within your enclosure.
