2J6901BC3F GNSS screw mount Antenna SMA-M 300cm

This high-precision antenna is engineered for advanced GNSS applications, supporting GPS, GLONASS, BeiDou, QZSS, Galileo, IRNSS, and SBAS across L1 and L5 bands. Its active multi-band design ensures superior accuracy, signal redundancy, and wide bandwidth, making it ideal for demanding environments such as autonomous vehicles, civil aviation, and safety-critical systems. The low-profile, ground plane independent construction and anti-rotation screw mount enable secure installation on a variety of surfaces, while the robust ASA UV-stable housing provides excellent protection against water, dust, and harsh weather conditions. The antenna delivers high active gain, low noise, and reliable performance for precise navigation and positioning in challenging scenarios.

Connections

GPS/GLO/BEI/QZSS/Galileo/IRNSS/L1L5

Connector & Cable

• Connector Type: SMA-Male
• Cable Length: 300cm
