Antennas RF Procurement Notes

Verify component authenticity through authorized channels as this part is officially discontinued. Confirm that existing inventory matches the original specifications before integration into legacy systems. Ensure compatibility with UHF female connectors during installation planning. Review technical documentation for any historical product change notices affecting performance characteristics.

Antennas RF Selection Notes

Select this model only when specific VHF frequency requirements between 44MHz and 50MHz are mandatory. Evaluate spatial constraints carefully due to the significant maximum height dimension. Consider the UHF connector type for interface compatibility with existing cabling infrastructure. Assess the need for high power handling capabilities relative to system output levels.

Antennas RF Part Context

This component belongs to the Lowband Ringo Antenna family produced by TE Connectivity. It serves as a specialized solution for very low frequency radio applications where vertical polarization and omnidirectional coverage are required. The design prioritizes durability and consistent radiation patterns across the designated VHF band.
