Antennas RF Procurement Notes

Verify that the specific variant ordered matches the required cable length and connector type, as the base model may be available with different configurations such as fixed cable lengths or alternative mounting styles. Confirm that the host receiver supports the 2.7 V to 5.5 V supply range to ensure proper antenna operation. Check for any specific firmware requirements on the receiving module to optimize signal processing for this active antenna type. Ensure environmental ratings meet the deployment conditions regarding temperature and humidity exposure during long-term use.

Antennas RF Selection Notes

Select the ANN-MS-1 when a robust, magnetically mountable active antenna is needed for L1 band GPS applications. It is ideal for designs prioritizing ease of installation and high performance across all major GPS constellations. Consider this component for projects where space constraints allow for a 48x40x13 mm footprint and where magnetic attachment offers a practical advantage over permanent fixing methods. Evaluate the need for an SMB connector interface against existing PCB layout constraints.

Antennas RF Part Context

The ANN-MS-1 belongs to the u-blox ANN-MS series of active antennas, which are specifically tuned to complement u-blox GNSS receiver modules. This series is designed to provide high-performance signal acquisition and tracking capabilities. The components in this family share common design principles focused on reliability and ease of integration into portable and vehicular electronics. They support multiple global navigation satellite systems operating in the L1 band.

Antennas RF Replacement Considerations

Direct substitutes include other u-blox active GPS antennas from the ANN-MS series, such as the ANN-MS-1-005, which may differ in cable length or packaging but maintain identical electrical characteristics. Cross-brand replacements require careful verification of gain, noise figure, and supply voltage compatibility to ensure equivalent performance in the target application.
