Centimeter Level RTK Beidou GPS Dual-frequency Surveying Mapping UAV Drone Helix Helical L1+L5 GNSS Antenna for Handheld Driving

Overview

RA82-T28A03 is a GPS , BeiDou, This four-system, full-band antenna for GLONASS and GALILEO is plug-and-play compatible with multiple domestic and international systems. It’s widely used in vehicle positioning, equipment positioning , and other applications .

The antenna unit adopts multi-pole amplification, 2 The advantages of high-level filtering, multiple feed points, and high-gain design ensure that the phase center coincides with the geometric center and the beam width of the directional pattern ensure that strong signals can be received even at low elevation angles.

It can also quickly locate in complex environments such as shade, viaducts, and high-rise buildings.

Antenna size: 59.3*28.2 , waterproof up to IP65 and other characteristics.

Hight Lights

• Ultra-light, Compact Design
  Weighing in at just ≤11 g, this GNSS helical antenna is exceptionally light and slim—ideal for handheld RTK mapping instruments and portable applications where size and weight matter.

• Low-Noise Amplification for High Sensitivity
  Featuring a low-noise amplifier (LNA) gain of 28 ± 2 dB and a noise figure of ≤2 dB, the antenna delivers enhanced signal sensitivity and better reception in challenging or weak-signal environments.

• 360° Coverage & Excellent Signal Fidelity
  With omnidirectional horizontal coverage (360°) and a good axial ratio (≤3 dB), it ensures reliable reception from all directions with high fidelity, minimizing signal distortion and maintaining consistent performance.

• Efficient Electrical Performance & Stability
  Operating at 3.3 V and drawing ≤30 mA, the antenna strikes a great balance between performance and power efficiency. Meanwhile, its VSWR of ≤2.0:1 and in-band flatness of ±2 dB contribute to stable signal output and minimal distortion across its operating band.
