2J6901BC2F GNSS screw mount Antenna SMA-M 300cm

This high-precision, low-profile external antenna is engineered for demanding GPS applications requiring centimeter-level accuracy. It supports Precise Point Positioning (PPP) of L1 and L2 bands with Real-Time Kinematic (RTK) satellite navigation, ensuring reliable performance for GPS, QZSS, GLONASS, BeiDou, Galileo, and SBAS standards. The antenna operates efficiently across 1227 MHz and 1561-1606 MHz frequencies, making it ideal for both receiving and transmitting in remote or challenging environments. Its robust design is perfect for land and hydrographic surveys, unmanned aerial vehicles, autonomous vehicles, and civil aviation, providing real-time error correction and precise data throughput even in obstructed or high-coverage areas.

• Centimeter-level accuracy for advanced navigation
• Multi-constellation GNSS support (L1/L2)
• Low noise figure and high active gain
• Ground plane independent and anti-rotation mounting
• Waterproof and dust-resistant housing for extreme environments

Connections

GPS/GLO/BEI/QZSS/Galileo/RTK/L1L2
