L1 GNSS Antennas – Single-Band Patch & Helix Modules for RTK, UAV and IoT

High-Precision L1 GNSS Antennas for Professional RTK Applications

L1 is the primary GNSS frequency transmitted by every major satellite constellation — GPS (1575.42 MHz), GLONASS G1, Galileo E1, BeiDou B1I/B1C, SBAS, and QZSS. A well-designed L1 antenna gives you full multi-constellation coverage from a single compact element, making it the preferred choice for weight-sensitive platforms, cost-constrained integrations, and applications where sub-meter to meter-level accuracy is acceptable.

Patch and Helix Form Factors

ELTEHS L1 antennas are available in two main form factors. Patch modules — ranging from 12 mm to 45 mm ceramic elements — are designed for PCB integration and enclosure mounting, with IPEX (U.FL) connectors and two-stage LNA gain between 28 dB and 38 dB. Helix antennas offer superior low-elevation signal reception and axial symmetry, making them the right choice for UAVs, robotics, and any platform where antenna orientation relative to the sky changes dynamically.

Applications: Reliable Performance for Surveying, UAVs, and Mapping

L1 single-band antennas are used in IoT asset trackers, entry-level RTK rovers, drone autopilot systems, handheld GNSS devices, and OEM module integration. For applications requiring centimeter-level RTK accuracy in real time, consider upgrading to an L1/L2 or L1/L2/L5 dual-band antenna from our multi-band collection.

Compatible and Ready for Integration

Whether you are building an RTK base station, upgrading a rover, or integrating GNSS into custom equipment, ELTEHS antennas offer full compatibility and professional-grade accuracy. Combine with our GNSS antennas by type or explore accessories for your installation.
