Antennas RF Procurement Notes

Verify the specific part number against official Calian documentation to confirm technical specifications. Ensure compatibility with existing RF interfaces and mounting requirements. Check manufacturer lead times as standard availability may vary. Confirm that the TNC female connector matches system cabling. Validate environmental ratings if used in harsh conditions.

Antennas RF Selection Notes

Select this model when dual-band GNSS reception is required for multiple global constellations. The pre-filtered design reduces out-of-band interference. Consider the panel mount form factor for fixed installations. Verify voltage requirements for the internal LNA before integration into the power supply design.

Antennas RF Part Context

This component belongs to the TW3872 series of dual-band GNSS antennas from Calian. It shares design principles with other models like the 33-3870-01-11 but offers specific frequency coverage for both L1 and L5 bands. The product line emphasizes high precision and durability for mission-critical applications.

Antennas RF Replacement Considerations

The TW3872E is a related variant using Accutenna technology. Verify connector type and gain specifications when substituting. Ensure voltage range compatibility for the LNA. Confirm that the replacement maintains the required polarization and mounting style.
