Q: Is this compatible with 868MHz LoRa modules?
A: Yes, it is specifically designed for the 868MHz band. Ensure your module has an SMA-K (Female) interface for compatibility.
Q: Can it be used for 915MHz systems?
A: While it may function, it is optimized for 868MHz. We recommend using a dedicated 915MHz antenna for the best performance in that band.
