Antennas RF Procurement Notes

Verify the specific frequency band support (868 MHz vs. 915 MHz) required by your target region before procurement. Ensure the mating device utilizes an SMA female port to match the male connector type. Confirm RoHS3 compliance status if environmental regulations apply to your manufacturing process. Cross-reference the physical dimensions against your enclosure design constraints.

Antennas RF Selection Notes

Select this antenna when a dedicated external solution is needed for LoRa networks rather than integrated PCB traces. Consider the 2.8 dBi gain as sufficient for moderate distance requirements without excessive size. Evaluate the SMA interface compatibility with existing module headers. Assess mounting options such as surface or pole mounting based on the installation environment.
