In the realm of precision surveying, where every millimeter counts, the choice of GNSS antenna can make or break the success of a project. Our Precision Surveying GNSS Antenna stands as a testament to engineering excellence, designed to deliver unparalleled accuracy, reliability, and versatility across a wide range of geospatial applications. Whether deployed in land surveying, construction layout, mapping, or infrastructure monitoring, this antenna redefines performance standards, ensuring that even the most demanding projects are executed with pinpoint precision.

At the core of this antenna’s capabilities lies its optimized frequency range, tailored to harness the power of key GNSS bands: 1575MHz, 1616MHz, and 2491MHz. These frequencies are critical for receiving signals from major global navigation systems, including GPS, GLONASS, Galileo, and BeiDou, enabling seamless multi-constellation tracking. This multi-band support not only enhances signal availability in challenging environments—such as urban canyons or dense foliage—but also minimizes errors caused by atmospheric interference, ensuring consistent accuracy even in dynamic conditions.

Complementing its frequency agility is a robust 5dBi gain, a key parameter that amplifies weak signals without introducing excessive noise. This gain strikes the perfect balance between sensitivity and stability, allowing the antenna to capture and process signals from satellites at low elevations, where data is often critical for resolving positional ambiguities. Whether operating in remote areas with limited satellite visibility or in complex landscapes, the antenna’s gain ensures that every available signal is utilized to its full potential, delivering positioning accuracy down to centimeter levels.

Versatility is another hallmark of this precision antenna, with support for a wide range of coaxial connectors and cables to suit diverse deployment scenarios. Users can choose from SMA, MCX, MMCX, HRS, and IPX connectors, ensuring compatibility with various receivers, data loggers, and communication devices. Additionally, the antenna is compatible with RF1.78, RF1.37, RF1.13, and RF0.81 coaxial cables, offering flexibility in cable length and routing to accommodate different project requirements—from short-range setups in urban construction sites to long-distance installations in remote survey areas.

The antenna’s compact dimensions—90mm x 13.5mm—make it ideal for applications where space is at a premium. Its sleek, low-profile design minimizes wind resistance, making it suitable for mounting on survey poles, drones, or moving vehicles without compromising stability. Despite its small size, the antenna does not sacrifice durability; it is built to withstand harsh environmental conditions, including extreme temperatures, moisture, and vibration, ensuring reliable operation in the field, day in and day out.

Polarization flexibility is yet another feature that sets this antenna apart. It supports both Right-Hand Circular Polarization (RHCP) and Linear Polarization, allowing users to optimize signal reception based on specific project needs. RHCP is particularly effective for mitigating the effects of signal reflection and multipath interference, which are common in urban or rugged terrains, while Linear Polarization offers advantages in certain fixed-installation scenarios where signal directionality is critical. This adaptability ensures that the antenna performs optimally across a wide spectrum of environments.

Performance metrics further underscore the antenna’s precision. With a Voltage Standing Wave Ratio (VSWR) of 1.5 or better, it ensures efficient power transfer between the antenna and the connected receiver, minimizing signal loss and maximizing sensitivity. The antenna operates on a DC voltage range of 3~5V, making it compatible with standard power sources used in surveying equipment, while its 50-ohm input impedance ensures seamless integration with most GNSS receivers, eliminating the need for additional matching components.

our Precision Surveying GNSS Antenna is more than just a component—it is a critical tool for professionals who demand the highest levels of accuracy and reliability in their geospatial work. Its advanced frequency support, optimal gain, versatile connectivity, compact design, and robust performance metrics make it the ideal choice for a wide range of applications, from land surveying and construction to precision agriculture and infrastructure monitoring. When precision matters, this antenna delivers—consistently, reliably, and without compromise.
