The TX-GR02-A is a premium Active Quadrifilar Helix Antenna engineered for high-precision GNSS applications. Unlike traditional patch antennas, its unique helical structure provides an ultra-wide beamwidth and exceptional circular polarization, ensuring your device stays locked onto satellite signals even during high-tilt maneuvers or in signal-shaded areas.
Whether it's for industrial drones (UAVs), robotic mowers, or handheld RTK survey tools, the TX-GR02-A delivers centimeter-level accuracy with professional-grade reliability.
1Full-Spectrum Global Positioning
Supports all major constellations including GPS (L1/L2), BDS (B1/B2/B3), GLONASS, and Galileo. One antenna for global compatibility.
2Unmatched Signal Stability
Featuring Quadrifilar Helix Technology, it offers superior gain at low elevation angles. Your signal stays strong even if the antenna isn't perfectly upright.
3High Gain, Low Noise
With a 32±2dB active gain and a noise figure ≤1.5dB, it captures even the weakest signals while the built-in band-pass filter rejects out-of-band interference.
4Industrial-Grade Wide Voltage
Supports an ultra-wide input range of 2.2V to 16V DC. It integrates seamlessly with 3.3V/5V digital systems or 12V automotive power sources without extra regulators.
5Compact & Rugged Design
Weighing in at a portable size (Φ27.5 x 59mm) with a standard SMA-J connector, it’s built to withstand harsh outdoor conditions (-40°C to +85°C).

Industrial UAVs
Perfect for mapping, inspection, and delivery drones requiring stable RTK data during flight

Autonomous Robotics
The go-to choice for smart lawnmowers, AGVs, and sweeping robots operating near walls or under trees

Precision Agriculture
Ensures tractors and automated farming machinery stay on the right path

Marine & Automotive
Reliable navigation for boats and vehicles, handling constant tilting and voltage fluctuations with ease.
