ATGGBL24138M-SMA-3

Antennas RF Overview

The YIC ATGGBL24138M-SMA-3 is an external RF antenna designed for GPS L1 and L2 bands, as well as general GNSS applications. It features a standard SMA male connector for interface compatibility. The unit includes a cable length of 3 meters to facilitate flexible installation positioning relative to the receiver module. Key electrical specifications include a Voltage Standing Wave Ratio (VSWR) of 2 and a return loss performance ranging from -3.85 dB to -39.62 dB across operational frequencies.

Antennas RF Feature Summary

• Supports dual-band GPS L1 and L2 signals alongside multi-system GNSS reception capabilities.
• Equipped with a durable 3-meter connecting cable for extended reach and mounting flexibility.
• Utilizes a standard SMA male connector to ensure broad compatibility with various receiver interfaces.

Antennas RF Applications

• Precision GPS navigation systems requiring L1/L2 signal integrity.
• GNSS surveying equipment for high-accuracy geospatial data collection.
• Maritime navigation receivers operating in multi-constellation environments.

Antennas RF Procurement Notes

Verify that the SMA male connector matches the receiving device's port type. Confirm that the 3-meter cable length meets the specific installation distance requirements between the antenna and the processing unit. Ensure the VSWR specification aligns with system sensitivity thresholds for optimal signal transmission efficiency.

Antennas RF Selection Notes

Select this model specifically when L1 and L2 band support is required for enhanced accuracy. Consider the 3-meter cable length as a fixed parameter during layout planning. Compare return loss metrics against other models if signal reflection minimization is critical for the specific application environment.

Antennas RF Part Context

This component belongs to the ATGGB series of RF antennas manufactured by YIC. The series encompasses various configurations for different frequency bands and connector types. This specific part number denotes the configuration optimized for L1/L2 GNSS reception with a standard SMA interface.

Antennas RF Replacement Considerations

The ATGGBL54138M-SMA-3 serves as a substitute offering L1+L5 band support instead of L2. Verify that the target application can utilize L5 signals or requires L2 specifically before swapping components.
