Product Description
Technical Details
The RAKARJ11 Sub-GHz antenna is designed for LoRa deployments in the 860–868 MHz band and is a practical choice for compact gateways, nodes, and dev boards using an RP-SMA antenna connector. With high efficiency and vertical polarization, it delivers stable performance in typical IoT installations where you want a simple, durable antenna without extra bulk.
It uses 50 Ω impedance and an RP-SMA male connector for easy integration across a wide range of LPWAN hardware. The radiator is copper, with a rugged TPE body and PA+ABS hinge/holder components, making it suitable for both prototyping and long-running field deployments.
If you’re selecting frequency by region, Kilo’s LoRaWAN regional guide and the LoRa Alliance regional parameters are good references for choosing the correct Sub-GHz band for your country.
