The TX-GR01-A is a professional-grade active quadrifilar helix antenna designed for mission-critical reliability. Its standout feature is the unique 3-point screw-mount structure (3-M2.5*6), ensuring maximum physical stability in high-vibration or high-speed environments. Combining advanced multi-feed point technology with an ultra-wide operating voltage (2.2V - 16V), it is the ultimate choice for RTK base stations, precision agriculture machinery, and professional UAV frame installations.
1Robust Screw-Mount Design
Built-in 3x M2.5 screw holes provide a secure mechanical connection, solving the instability issues of magnetic or adhesive mounts in high-vibration scenarios.
2Full-Constellation Support
Supports GPS L1/L2, BDS B1/B2/B3, GLONASS, and Galileo, enabling true global centimeter-level positioning accuracy.
3Stable Phase Center
The symmetrical quadrifilar helix structure minimizes measurement errors to the millimeter level—the cornerstone of high-precision RTK operations.
4Superior Anti-Interference
Equipped with a high-performance LNA and integrated band-pass filters, achieving out-of-band rejection ≥30dB to maintain signal lock in complex electromagnetic environments.
5Wide 16V Voltage Range
Supports 2.2V to 16V DC input, allowing direct integration with 12V vehicle power systems without additional voltage regulators.
5Industrial Durability (IP67 & UV Resistant)
Encased in high-performance, UV-resistant materials for long-term outdoor exposure in extreme weather conditions (-40°C to +85°C).
Fixed RTK Base Stations
Provides long-term physical position stability through its secure screw-mount design
Precision Agriculture & Heavy Machinery
Ensures consistent positioning for tractors and harvesters in high-vibration farming environments
Industrial UAVs
Serves as the reliable RTK positioning core for mapping, surveying, and inspection drones
Autonomous Vehicles
16V wide-voltage support allows for direct connection to automotive battery systems
