Antennas RF Procurement Notes

Verify that the specific order includes the RP-SMA female connector variant, as connector types can vary within product families. Confirm RoHS compliance status at the time of purchase to ensure adherence to current environmental regulations. Check mechanical dimensions against enclosure constraints, noting the 87.00mm height. Ensure the receiving facility has appropriate handling procedures for RF components to maintain signal integrity upon delivery.

Antennas RF Selection Notes

Select this model when dual-band coverage in the 2.4 GHz and 5.8 GHz bands is required for Wi-Fi applications. The tilt feature is advantageous for optimizing radiation patterns in constrained spaces. Compare against single-band alternatives if only one frequency range is needed. Consider the RP-SMA interface compatibility with existing board designs or cable assemblies before finalizing the selection.
