Product Description
Technical Details
The RAK PCB antenna (MHF-4) is a compact, high-performance antenna designed for LoRa® and LoRaWAN® applications. It uses an MHF-4 connector and can be easily connected to many RAK modules, including the WisDuo modules RAK11160, RAK11720, and RAK3112, as well as the WisBlock Core modules RAK11162 and RAK3312.
For other module versions, an alternative variant with an MHF-1 connector is available.
The antenna supports the 902–928 MHz frequency range used in North America and Australia. It features linear polarization, 50-ohm impedance, and delivers stable performance with good efficiency in a very small form factor.
Note: MHF connectors are generally compatible with IPEX connectors and are often interchangeable in many hardware designs.
