Antennas RF Procurement Notes

This component has been officially declared obsolete by the manufacturer as of September 27, 2022. Procurement is restricted to remaining stock or secondary market sources. Verification of part authenticity and condition is critical due to the discontinued status. Buyers should confirm compatibility with existing mounting hardware and connector interfaces before acquisition.

Antennas RF Selection Notes

Designers must account for the discontinuation of this specific model when planning new deployments. Replacement strategies should prioritize components with identical mechanical dimensions and electrical specifications to ensure seamless integration. Compatibility with UHF female connectors and bracket mounting systems remains a primary selection criterion for substitute parts.

Antennas RF Part Context

The CRX450B belongs to the CRX450 series of RF antennas from TE Connectivity. This series focuses on providing reliable omnidirectional coverage for UHF frequencies.
