Antennas RF Procurement Notes

Verify the specific model suffix against official TE Connectivity documentation to ensure correct frequency range and physical specifications. Confirm RoHS compliance status and environmental ratings prior to integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Ensure mounting hardware compatibility with the NMO base interface.

Antennas RF Selection Notes

Select this component when high-gain UHF performance is required in space-constrained installations. The low-profile dome design suits vehicles where aerodynamic drag is a concern. Consider the 410-425MHz operational bandwidth to match existing network frequencies. Evaluate the NMO mounting requirement against available surface types.

Antennas RF Part Context

This antenna belongs to the Phantom Elite series, which emphasizes durability and advanced signal processing features. The ETRA4103 variant specifically targets the lower UHF spectrum, distinguishing it from standard 410-430MHz models. It represents a specialized solution for professional mobile radio operators requiring consistent coverage.

Antennas RF Replacement Considerations
