iPEX to RP-SMA / SMA Connector

Reliable Antenna Connection for Your LoRa Module

This RF coaxial cable connects your LoRa module to an external antenna. It features a compact iPEX connector (MHF-1 or MHF-4) on one end and a RP-SMA or SMA connector with a nut and washer on the other end, allowing for secure mounting on an enclosure.

Whether you're building with WisDuo or WisBlock modules, this cable helps ensure a stable and high-quality RF signal—especially important in outdoor or industrial environments.

Now Available in MHF-4 Version

Most earlier RAK modules used MHF-1 (iPEX1) connectors. We now support MHF-4 (iPEX4), a smaller and more compact version used in newer modules.

FAQ

Q: What’s the difference between MHF-1 and MHF-4?
A: MHF-4 is smaller than MHF-1. It’s commonly used in newer RAK modules that require a more compact form factor.

Q: Can I use an MHF-1 cable on an MHF-4 module?
A: No. The connectors are physically different and not interchangeable.

Q: Is this cable compatible with other antenna types?
A: The cable ends in an RP-SMA or SMA connector, which fits most external LoRa antennas. Make sure your antenna matches the connector type.
