Antennas RF Procurement Notes

Verify the specific manufacturing date code and RoHS compliance status upon order confirmation. Ensure the receiving facility handles electrostatic discharge precautions during storage and installation. Confirm that the 15 cm RG-178 cable length meets the mechanical constraints of the final assembly. Cross-reference the 90-degree MMCX orientation with the mating port on the host PCB to ensure proper alignment.

Antennas RF Selection Notes

Select this model when space constraints require a low-profile antenna solution. The ground plane independence simplifies integration into diverse chassis designs without complex grounding requirements. The fixed 15 cm cable length suits applications where the antenna must be positioned away from the main circuit board but within close proximity. Verify that the 10 W power rating aligns with the transmitter specifications of the target system.
