Procurement Notes
Verify the specific frequency band requirements against the target satellite constellations before procurement. Confirm that the power supply provides stable DC voltage within the 2.8 V to 6.0 V operating range. Ensure the installation environment accommodates the conical permanent mount geometry. Check connector compatibility for the TNC female interface on the receiving equipment.
Selection Notes
Select this model when comprehensive multi-constellation support is required for critical timing or positioning tasks. The integrated LNA makes it suitable for long cable runs where signal loss is a concern. Consider the IP rating and environmental sealing if deployed in harsh outdoor conditions. Compare gain specifications against other dome antennas if higher directivity is needed.
Part Context
This component belongs to the Amphenol PCTEL GNSS antenna portfolio, specifically engineered for robust performance in global navigation satellite systems. It is part of their industrial IoT and transportation connectivity solutions, focusing on reliable data acquisition for time-sensitive applications across various sectors.
Replacement Considerations
Consult official Amphenol PCTEL documentation for cross-reference part numbers. Verify mechanical mounting dimensions and electrical interface compatibility before substituting. Ensure any alternative model maintains equivalent LNA performance and multi-constellation support capabilities.
