Engineered for stable tracking in obstructed, noisy and outdoor environments.
Strong Low-Elevation Reception
High passive gain and wide beamwidth deliver excellent low-elevation reception. The antenna still receives satellite signals normally in heavily obstructed environments.
Wide Operating Bandwidth
The passive antenna supports multi-system, multi-frequency operation, especially the global B3 frequency, L5 and L-Band, which greatly improves system stability.
High Out-of-Band Rejection
Effectively avoids instability caused by interference from communication base stations and other signals.
IP67 Rugged Housing
A compact, reliable structure with an IP67 waterproof, dustproof and UV-resistant housing for long-term use in harsh outdoor conditions.
Accurate Phase Center
Phase center error of ±2 mm and an axial ratio of ≤3 dB support precise, repeatable measurements.
Easy Installation
Standard 5/8″ × 11 mount and TNC-K connector fit common survey poles, brackets and receivers.
Heavily Obstructed Sites
Keeps tracking low-angle satellites near trees, buildings and cranes.
Multi-System Receivers
Covers GPS, BDS, GLONASS, Galileo and L-Band in one antenna.
Interference-Heavy Areas
High out-of-band rejection protects the receiver near cellular towers.
Long-Term Outdoor Use
−40 °C to +85 °C operation with IP67 sealing.
Moving Platforms
Compact and light for UAVs, vehicles and agricultural machines.
Fixed Monitoring
Stable for bridge, geological and port monitoring stations.
Why Choose This Survey GNSS Antenna?
When a receiver loses lock or drifts, the antenna is often the cause. This high-precision GNSS antenna pairs a wide-band passive element with a low-noise amplifier tuned for L1 and L2, so your RTK or geodetic system gets clean signals from every constellation.

FAQ About GNSS Antennas
Which satellite systems does this GNSS antenna support?
GPS L1/L2/L5, BDS B1/B2/B3, GLONASS L1/L2/L3, Galileo E1/E5a/E5b/E6 and L-Band. It meets surveying equipment requirements for BDS-3 and multi-system compatibility.
Does it work in obstructed environments?
Yes. High passive gain and a wide beamwidth give excellent low-elevation reception, so it can still receive satellite signals normally in heavily obstructed areas.
What connector, mount and power does it use?
It uses a TNC-K connector and a 5/8″ × 11 mount. The built-in LNA runs on DC 3.3–12 V at ≤50 mA.
Is it suitable for harsh outdoor use?
Yes. The housing is IP67 waterproof, dustproof and UV-resistant, with an operating range of −40 °C to +85 °C.
Can I request a sample or volume pricing?
Yes. Click any quote button on this page, send us your quantity and application, and we will reply with pricing and the datasheet.
