Discover the BNTWL130M 4-channel anti-jamming antenna. BDS/GPS/GAL support, ≥110dB single interference resistance, ≤16.5W power, 130x130mm/540g.
Navigation precision depends on clear signals. When interference devices turn on, standard antennas fail. The BNTWL130M is a dedicated solution built to fix this exact problem. It is a dual-frequency, four-channel satellite navigation anti-jamming antenna designed to keep positioning data stable and reliable under any conditions. Whether you are dealing with accidental interference or planning a complex deployment, this unit delivers consistent performance.
One of the core strengths of the BNTWL130M is its frequency diversity. It supports the BDS_B1, GPS_L1, GAL_E1, and GPS_L2/L5 bands. If your project requires the BeiDou B3 band, you can add it as an optional upgrade. This multi-system coverage means the antenna works smoothly with BeiDou, GPS, and Galileo systems. It eliminates the need for separate antenna modules, which reduces overall hardware footprint and simplifies system wiring. This flexibility makes it easy to adapt to different regional navigation setups.
In modern electronic environments, jamming protection is essential. The unit features a powerful anti-single broadband interference capability rated at 110dB or higher. When jammers increase, it still fights back effectively against three broadband interferences, maintaining at least 95dB of resistance. This layered defense mechanism prevents signal loss and maintains continuous tracking in complex electromagnetic environments. It acts like a filter, blocking the noise and allowing clean satellite signals to pass through. The strong defense ensures your system does not suffer blind spots when it matters most.
Hardware deployment often faces space and weight limits. The antenna’s square design measures 130.0mm by 130.0mm by 32.0mm. With a weight of no more than 540g, it is highly portable and easy to mount. Power consumption is another key factor, especially for mobile platforms. The BNTWL130M runs on ≤16.5W. This low power draw minimizes battery drain and reduces heat issues on drones or mobile vehicles. The light blue casing also offers good weather resistance. The small size means it can be easily installed in tight spaces.
The four channels work together to process signals from different bands simultaneously. This parallel processing prevents delays and ensures data synchronization. The internal circuitry manages complex filtering tasks in real time. This design choice demonstrates excellent engineering and thermal management. By handling dual-frequency signals efficiently, the antenna reduces the computational burden on your main receiver. It provides clean, usable data that is ready to feed into your navigation system. The channels are tuned to deliver a constant, uninterrupted signal stream.
This hardware is best suited for users who cannot afford signal loss. It works well for autonomous vehicles where continuous positioning is required for safety. Surveying drones also benefit from the lightweight design. Critical infrastructure monitoring relies on it to maintain stable timing signals. In electronic warfare environments, military applications that depend on precise timing and positioning will find this antenna invaluable. It acts as a reliable signal protector, filtering out the clutter and providing accurate location data. Telecom base stations can also use it for network synchronization.
For the best results, install the antenna with a clear view of the sky. Keep cables short and well-shielded to maintain anti-jamming performance. Check connectors periodically for corrosion or looseness. Since power consumption is low, there is no need for dedicated cooling, but keeping the casing clean helps with heat dissipation. In wet environments, ensure the seals remain intact. Use the provided mounting holes to secure the unit firmly. These simple steps will extend the lifespan of the equipment.
Choosing the right anti-jamming antenna is critical. The BNTWL130M combines multi-constellation support, strong interference suppression, and a compact physical size. It offers a perfect balance of performance and practicality. For engineers looking to harden their navigation systems without exceeding budget or space limits, this model is a highly competitive choice. Reliable navigation is within reach.
