BNTWL340 Dual-Frequency 16-Channel Anti-Jamming Antenna. BDS_B1, GPS_L1, GAL_E1, GPS L5. ≥110dB single & ≥95dB fifteen-broadband resistance. 340x340x65mm, ≤70W, ≤4.8kg.
In high-precision navigation, dual-frequency capability is what separates standard equipment from professional-grade hardware. The BNTWL340 dual-Frequency sixteen-channel Anti-Jamming Antenna is engineered to operate in the most punishing RF environments. This model represents a significant leap forward in protecting critical GNSS signals. It is not just about receiving data; it is about guaranteeing that the data remains uncorrupted and trustworthy under extreme duress.
What makes this hardware stand out is its multi-constellation and multi-band support. By default, it covers BDS_B1, GPS_L1, GAL_E1, and GPS L5. Furthermore, it offers the flexibility of optional upgrades to include GPS_L2 and BDS_B3. Operating on dual frequencies allows the receiver to correct ionospheric errors automatically, which drastically improves positioning accuracy. But more importantly, having access to multiple frequencies provides redundancy. If one band is compromised by interference, the system can seamlessly rely on another to maintain a solid navigation lock.
The core mission of any anti-jamming system is to defeat hostile signals. The BNTWL340 does this with impressive statistics. It delivers an anti-single broadband interference capability of ≥110dB. This means it can effectively cancel out a highly focused, powerful jamming signal aimed at a specific frequency. Even when facing a coordinated, multi-source attack, the antenna holds its ground. It provides ≥95dB of resistance against fifteen separate broadband interference sources. This advanced spatial filtering ensures that your receivers only process genuine satellite signals.
Unlike smaller models, the BNTWL340 is built for maximum array performance. It utilizes a large, square footprint measuring 340.0mm×340.0mm×65.0mm. This expansive surface area allows for a larger physical antenna array, which is mathematically necessary to achieve such high levels of interference cancellation. To drive this complex processing, the unit draws a maximum of ≤70W. While this is a higher power requirement, it is a small price to pay for unwavering signal stability. At ≤4.8kg, it remains manageable for permanent installations and large vehicle mounting.
Where does this antenna truly shine? Its robust specifications make it perfect for military and defense applications, where electronic warfare is a constant threat. It is also heavily utilized in high-precision surveying and mapping, where dual-frequency accuracy is non-negotiable. Additionally, it serves as an excellent solution for critical infrastructure like fixed reference stations, telecommunications timing networks, and heavy construction machinery operating in remote locations. Whenever signal loss is simply not an option, this hardware provides the necessary backbone.
If your operations require the highest level of signal integrity, the BNTWL340 anti-jamming antenna is the logical choice. Its dual-frequency tracking, massive 16-channel processing, and heavy-duty build quality make it a formidable defense against signal interference. It ensures that your positioning, navigation, and timing data remain secure, regardless of the electromagnetic environment.
