Antennas RF Procurement Notes

Verify availability status as this part number is listed as discontinued by the manufacturer. Confirm compatibility with existing NMO mounts before procurement. Check for valid replacement part numbers from TE Connectivity or authorized distributors to ensure long-term supply chain stability for ongoing projects.

Antennas RF Selection Notes

Select this component only if the specific 430-450MHz frequency range matches system requirements. Ensure mechanical clearance allows for the 14-inch height. Verify that the NMO base interface aligns with the intended mounting surface. Consider alternative models if active production status is required for future maintenance.

Antennas RF Part Context

This antenna is part of TE Connectivity's portfolio of RF solutions for mobile communication applications. It serves as a specialized component for UHF band operations, distinct from other series like the Phantom dome antennas. The product represents legacy hardware within the broader antenna catalog.

Antennas RF Replacement Considerations

B4305CN offers similar specifications with higher gain and length. TRAB4303 provides a dome style alternative with identical mounting and frequency characteristics.
