Antenna description


Active Multi-Band GNSS Antenna Designed With Superior Accuracy and Reliability

The 2J6901BC3F is specifically designed for high precision and advanced signal technologies that cover all major GNSS bands, including GPS, GLONASS, BeiDou, QZSS, Galileo and IRNSS. The 2J6901BC3F operates at high efficiency within 1176 MHz and 1561-1606 MHz frequencies with low-profile antenna design and high-quality screw mount.

The L5 band is the first choice for new and advanced GPS receivers as it is designed to meet the demand for high-performance applications such as safety-of-life transport and autonomous vehicles. By combining L1, L5 and SBAS (Satellite-Based Augmentation System), the antenna achieves superior accuracy, improved signal redundancy, and greater bandwidth while delivering correction data such as satellite position errors, clock/timing errors, and estimations of degradation parameters.

Suggested applications include:

- Safety-Critical Systems & Transportation
- Autonomous Vehicles
- Agriculture
- Navigation
- Civil Aviation

Compatibility Standards

-GPS(L5), BeiDou(B2a), QZSS(L5), Galileo(E5a), IRNSS(L5)

-GPS(L1C), GLONAS(L1OF), BeiDou(B1), QZSS(L1C), Galileo(E1), SBAS (L1) 


The 2J6901BC3F offers low noise figures of 1.6 db @3V, ESD 2kV protection and a high rejection pre-filter without compromising active gains of 28 dB @3V.

Installation and Durability

The 2J6901BC3F is enclosed in a robust, waterproof and dust resistant ASA UV-stable housing that measures 80 x 74 x 25.6 mm, protecting the antenna in the most extreme environmental conditions. The anti-rotation screw mount and ground plane independence allow this external antenna to be installed securely on a wide range of surfaces without restrictions. The 2J6901BC3F is delivered with a standard SMA-Male connector and a 300 cm long LL100 cable (custom options available). Please contact our highly skilled team members to assist with customization and integration needs. 2J Antennas recognizes the importance of the environment and has implemented steps to further sustainability making us fully RoHS and Reach compliant.
