Antennas RF Procurement Notes

This component is officially listed as discontinued by the manufacturer. Availability is restricted to remaining stock or secondary market sources. Verify end-of-life status and obsolescence notices before integration into new designs. Sourcing may involve limited quantities with potential supply chain variability. Confirm current availability through authorized distributors prior to procurement planning.

Antennas RF Selection Notes

Select this model only for legacy system maintenance or replacement scenarios requiring exact dual-band VHF/UHF performance. The NMO mount requires compatible vehicle or equipment bases. Consider active replacements if new production is planned due to discontinuation status. Ensure mechanical fitment for the 965.20mm height constraint.

Antennas RF Part Context

The C144/440CRO belongs to TE Connectivity’s RF antenna portfolio, specifically targeting mobile communication needs. It serves as a specialized solution for dual-frequency operations without requiring separate single-band units. The product line emphasizes robust construction for outdoor and vehicular environments.

Antennas RF Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is discontinued, no direct official equivalents are listed. Evaluate generic NMO-mount whip antennas with matching frequency ranges for functional substitution.
