The Square Patch GNSS Antenna, model TX-G011, is a high-quality positioning device originating from Guangdong, China, under the brand TOXU. It is designed as both a GPS/GNSS Antenna and a GNSS RTK Antenna, making it a versatile choice for various precision positioning applications.

One of the notable features of this antenna is its diverse coaxial connector options, including SMA, MCX, MMCX, HRS, and IPX. This wide range of connectors ensures seamless compatibility with different types of GNSS receivers, data loggers, and other related equipment. Whether used in professional surveying tools or portable navigation devices, it can be easily connected, reducing setup time and enhancing operational efficiency.

In terms of gain, the antenna delivers 3.4dbi at 1176MHz and 5dbi at 1575MHz. This frequency-specific gain ensures optimal signal reception at the key GNSS bands, allowing it to capture weak satellite signals effectively. The varying gain values are tailored to the characteristics of each frequency, ensuring stable and reliable positioning performance even in challenging environments with signal obstructions.

The frequency range of 1176/1575MHz covers important GNSS bands, enabling the antenna to work with multiple satellite systems such as GPS, Galileo, and BeiDou. This broad frequency coverage enhances its positioning accuracy and reliability by leveraging signals from different satellites, reducing the impact of signal interference or blockages.

When it comes to coaxial cables, the antenna is compatible with RF1.78, RF1.37, RF1.13, and RF0.81 types. This flexibility in cable selection allows users to choose the most suitable option based on their specific application needs, such as cable length, flexibility, and signal loss requirements. Whether working in tight spaces that demand a more flexible cable or covering longer distances that require minimal signal loss, this antenna can be easily configured.

With a PCB dimension of 70*70mm, the square patch design of the antenna offers a compact and space-saving solution. Its small size makes it easy to integrate into various devices and systems, whether mounted on a surveying pole, installed in a vehicle, or embedded in a portable device. The square shape also provides stable mechanical performance, ensuring secure installation and reliable operation.

Polarization options of RHCP (Right-Hand Circular Polarization) and LINE (Linear Polarization) further enhance the antenna's adaptability. RHCP is particularly effective for receiving satellite signals, as it minimizes signal loss caused by polarization mismatch, ensuring efficient signal capture from satellites. LINE polarization, on the other hand, is suitable for certain terrestrial applications, making the antenna versatile across different usage scenarios.

The VSWR (Voltage Standing Wave Ratio) of 1.5 indicates excellent signal matching between the antenna and the connected equipment. A low VSWR value ensures minimal signal reflection, maximizing signal transmission efficiency and reducing signal loss. This contributes to stable signal reception and transmission, improving the overall accuracy and reliability of positioning data.

Operating on a DC voltage of 3~5V, the antenna is compatible with most standard power supplies used in GNSS equipment. This wide voltage range ensures reliable operation even when there are slight fluctuations in the power source, making it suitable for use in remote areas or field environments where power stability may be a concern.

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

 the Square Patch GNSS Antenna (TX-G011) from TOXU combines versatility, performance, and compact design, making it an excellent choice for a wide range of GNSS applications, including surveying, mapping, navigation, and precision agriculture. Its diverse connector options, frequency-specific gain, broad frequency coverage, and reliable performance ensure accurate and stable positioning in various environments.
