The RTK Marine Antenna Nautical Surveying GNSS Antenna, also known as the GLONASS BDS Antenna, is a high-performance device tailored for precise nautical surveying and marine applications. With its robust design and advanced features, it ensures reliable positioning even in the challenging marine environment.

This antenna offers excellent connectivity with a TNC-K connector, which provides a secure and stable connection to compatible marine equipment. The TNC-K connector is well-suited for marine use, as it offers good resistance to vibration and environmental factors, ensuring uninterrupted signal transmission during nautical operations.

Constructed from ABS material, the antenna is built to withstand the harsh conditions of the marine environment. ABS is known for its durability, resistance to corrosion, and ability to handle exposure to water, salt, and UV rays. This makes the antenna highly reliable for long-term use on boats, ships, and other marine vessels, where it is constantly exposed to the elements.

Featuring circular polarization, the antenna is optimized for receiving signals from various satellite systems. Circular polarization is particularly advantageous in marine environments, as it minimizes signal loss caused by reflections from the water surface and ensures consistent reception of satellite signals, even when the antenna is in motion or tilted due to waves.

The product supports a wide range of satellite systems and frequency bands. Its frequency ranges include GLONASS (L1, L2), Galileo (L1, E5b, E5a), and it can be customized to meet specific requirements. This broad frequency coverage allows the antenna to leverage signals from multiple satellite constellations, enhancing positioning accuracy and reliability. Whether conducting nautical surveys in coastal waters or open seas, the antenna can capture signals from various satellites to provide precise location data.

With a gain of ≥5dBi, the antenna ensures strong signal reception, even in areas where satellite signals may be weak or affected by interference. The high gain helps amplify weak signals, enabling reliable positioning in challenging marine environments such as areas with heavy cloud cover or near large structures. Additionally, the LAN gain of 402dBi further enhances signal processing, contributing to more accurate and stable positioning results.

The VSWR (Voltage Standing Wave Ratio) of 2.0 indicates good signal matching between the antenna and the connected equipment. A VSWR of 2.0 ensures that most of the signal power is transmitted and received with minimal reflection, maximizing signal efficiency and reducing signal loss. This is crucial for maintaining strong and stable connections in marine applications, where signal quality can be easily affected by environmental factors.

The antenna comes in a white color, which not only gives it a clean and professional appearance but also helps reflect sunlight, reducing heat absorption. This can contribute to better performance in hot weather conditions, ensuring the antenna operates within its optimal temperature range.

It is available in two dimension options: D147 x 62MM and D160*62mm. These dimensions make the antenna compact enough to be installed on various marine vessels without taking up excessive space, while still providing sufficient surface area for effective signal reception. The choice of dimensions allows for flexibility in installation, depending on the available space and specific requirements of the marine equipment.

the RTK Marine Antenna Nautical Surveying GNSS Antenna is a reliable and high-performance solution for nautical surveying and marine applications. Its TNC-K connectivity, ABS construction, circular polarization, broad frequency coverage, high gain, and suitable dimensions make it an ideal choice for ensuring precise and stable positioning in the demanding marine environment. Whether used for hydrographic surveys, vessel navigation, or offshore operations, this antenna delivers consistent and accurate results.
