YEGN103W8A

Antennas RF Overview

The Quectel YEGN103W8A is an active, low-profile external GNSS antenna designed for multi-constellation navigation. It supports dual frequency bands: 1.164 GHz to 1.3 GHz and 1.525 GHz to 1.606 GHz, covering GPS, GLONASS, Galileo, and other GNSS systems. The unit features a dome mechanical form with magnetic mounting, measuring 71.43 mm in height. It includes a 3-meter RG174 cable terminated with an SMA male connector. The integrated LNA provides a gain of 40 ±4 dB. Rated IP67, it operates between -40°C and +85°C with RHCP polarity and 50 Ohms impedance.

Antennas RF Procurement Notes

Verify the specific connector type required for your application interface, as documentation references both SMA male and TNC female variants for this model number. Confirm that the 3-meter RG174 cable length aligns with your system layout constraints. Ensure the operating temperature range of -40°C to +85°C meets your environmental requirements. Check RoHS compliance status if restricted substances are a concern. Validate that the magnetic mount strength is sufficient for the intended surface material and vibration conditions.

Antennas RF Selection Notes

Select this component when a compact, magnetically attachable GNSS solution is required for mobile assets. The active LNA makes it suitable for applications where the receiver is located at a distance from the antenna. The dual-band support ensures compatibility with modern multi-constellation receivers. Consider the IP67 rating for outdoor exposure. The low profile minimizes aerodynamic drag and visual impact compared to whip antennas.

Antennas RF Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. When evaluating alternatives, ensure the replacement supports the same dual-frequency bands (1.164–1.3 GHz and 1.525–1.606 GHz). Verify that the substitute offers comparable LNA gain and maintains IP67 rating for environmental sealing. Match the connector type and cable length to avoid adapter usage.
