ANT-GNRM-L125A-3

Antennas RF Overview

The ANT-GNRM-L125A-3 is a remote active GNSS antenna manufactured by TE Connectivity Linx. It supports GPS, Galileo, GLONASS, Beidou, NavIC, and QZSS systems with dual-band frequency coverage spanning 450MHz to 1.6GHz. The unit features an SMA male connector and a magnetic mount installation type. Key electrical parameters include a maximum gain of 33.5dBi, VSWR values ranging from 1.2 to 1.5, and return loss between -14.5dB and -19.9dB. It operates within a temperature range of -40°C to +85°C and includes a 3-meter cable length.

Antennas RF Feature Summary

• Dual-band frequency coverage supporting multiple global navigation satellite systems including GPS, Galileo, GLONASS, and BeiDou.
• Integrated low-noise amplifier (LNA) providing high signal gain for improved reception sensitivity.
• Magnetic mounting design allowing for flexible and non-invasive installation on metallic surfaces.
• IP67 rated enclosure ensuring protection against dust ingress and temporary immersion in water.

Antennas RF Applications

• Vehicle tracking and fleet management telematics
• Maritime navigation and positioning systems
• Aviation navigation equipment
• Precision agriculture machinery guidance

Antennas RF Procurement Notes

Verify the specific suffix configuration matches the required cable length and connector type before ordering. Confirm that the operational environment falls within the specified temperature range and humidity limits. Ensure compatibility with the host receiver's voltage supply requirements for the integrated LNA. Check for any regional regulatory compliance certifications relevant to the deployment location.

Antennas RF Selection Notes

Select this model when high-gain performance is required for remote or mobile applications where line-of-sight may be obstructed. The magnetic mount offers a convenient alternative to permanent fixtures. Consider the 3-meter cable length as a fixed parameter; custom lengths are not standard. Evaluate the need for dual-band support if interference from lower frequencies is a concern in the operating environment.

Antennas RF Part Context

This component belongs to the RM Magnetic Mount Active GNSS Antennas series from Linx Technologies. The series is designed for robust outdoor and mobile use cases requiring reliable satellite signal acquisition. It complements other passive and active antennas in the portfolio by offering enhanced gain through internal amplification suitable for challenging signal environments.

Antennas RF Replacement Considerations

Consult the official Linx Technologies Antenna Cross Reference Guide for verified substitute part numbers. Direct replacements must match the SMA male interface, magnetic mounting style, and dual-band frequency support. Verify that any alternative maintains equivalent gain and IP67 rating specifications.
