The Surveying GNSS Antenna is a high-performance device tailored for precision surveying applications, integrating advanced features to ensure accurate and reliable positioning in diverse environments. Its design prioritizes functionality, compatibility, and durability, making it an essential tool for professionals in geospatial mapping, construction, and land surveying.

A key feature of this antenna is its versatile coaxial connector options, including SMA, MCX, MMCX, HRS, and IPX. This wide range of connectors ensures seamless integration with various surveying equipment, such as GNSS receivers, data loggers, and mapping tools. Whether working with compact handheld devices or larger stationary systems, the antenna can be easily connected, reducing setup time and enhancing workflow efficiency.

With a gain of 5dBi, the antenna strikes an optimal balance between signal reception and noise reduction. This gain level is well-suited for surveying tasks, as it captures weak satellite signals effectively without amplifying background interference. It ensures stable connectivity even in areas with partial obstructions, such as urban canyons or lightly wooded regions, where maintaining a strong signal is crucial for accurate measurements.

The frequency range of 1575MHz/1616MHz/2491MHz allows the antenna to operate with multiple GNSS constellations, including GPS, GLONASS, Galileo, and BeiDou. This multi-frequency support enhances positioning accuracy by leveraging signals from various satellites, reducing errors caused by signal blockages or atmospheric disturbances. It enables precise measurements even in challenging conditions, making it ideal for high-precision surveying projects.

The antenna is compatible with different coaxial cable types, including RF1.78, RF1.37, RF1.13, and RF0.81. This flexibility in cable selection allows users to choose the most suitable option based on the specific requirements of their surveying setup, such as cable length, flexibility, and signal loss. Whether working in tight spaces that demand a flexible cable or covering long distances that require low signal loss, the antenna can be configured accordingly.

Measuring 90*13.5 in dimension, the antenna is compact and lightweight, making it easy to transport and install. Its small form factor allows for flexible mounting on surveying poles, tripods, or vehicles, without adding excessive bulk or weight. This portability is particularly valuable for fieldwork, where mobility and ease of setup are essential.

Polarization options of RHCP (Right-Hand Circular Polarization) and LINE (Linear Polarization) further enhance the antenna's adaptability. RHCP is ideal for receiving signals from satellites, as it minimizes signal loss due to polarization mismatch, while LINE polarization is suitable for certain terrestrial applications. This versatility ensures the antenna can perform optimally in a wide range of surveying scenarios.

With a VSWR (Voltage Standing Wave Ratio) of 1.5, the antenna exhibits excellent signal matching, minimizing signal reflection and ensuring efficient power transfer between the antenna and connected equipment. This low VSWR value contributes to stable signal reception and transmission, reducing data errors and improving the overall reliability of surveying measurements.

The antenna operates on a DC voltage of 3~5V, which is compatible with most standard surveying equipment power supplies. This wide voltage range ensures reliable operation even when power sources fluctuate, making it suitable for use in remote areas where stable power may be a challenge.

Featuring an input impedance of 50 ohms, the antenna is perfectly matched to most GNSS receivers and related equipment, ensuring maximum signal transfer efficiency. This impedance matching reduces signal loss and interference, further enhancing the accuracy and reliability of positioning data.

the Surveying GNSS Antenna combines versatility, precision, and durability to meet the demanding requirements of modern surveying applications. Its wide range of connectors, multi-frequency support, compact design, and excellent signal performance make it a valuable tool for professionals seeking accurate and reliable positioning data in any environment.
