Get the BNTWL100M 4-channel GNSS anti-jamming antenna. Covers BDS_B1, GPS_L1, GAL_E1. Features ≥95dB anti-three-interference, 100x100x26mm size, ≤8W power, and ≤300g weight.
When standard GNSS receivers fail under heavy electromagnetic pressure, system integrators need a more robust solution. The BNTWL100M four-channel satellite navigation anti-jamming antenna is engineered for heavy-duty platforms. It offers a larger footprint and higher power handling capacity than compact models, making it a dependable choice for industrial and military-grade deployments where signal loss is simply not an option.
This unit tracks three critical frequency points simultaneously: BDS_B1, GPS_L1, and GAL_E1. By monitoring multiple constellations, the antenna ensures continuous positioning data even if a specific satellite network is degraded or blocked. The four-channel architecture effectively manages phase alignment and maintains strong signal integrity across all supported bands. This redundancy is vital for dynamic platforms that frequently move through urban canyons or dense vegetation.
The BNTWL100M shines in its defensive hardware. It delivers an anti-single broadband interference capability of ≥110dB and steps up the anti-three-broadband interference capability to ≥95dB. This elevated threshold means the internal filtering array can cancel out multiple simultaneous jamming threats. Field operators will appreciate the hardware-level mitigation, which acts instantly without draining host processor resources. It effectively blocks out unwanted RF noise, ensuring the tracking loop remains locked.
Unlike ultra-lightweight alternatives, this model utilizes a 100.0mm × 100.0mm × 26.0mm chassis. The increased surface area assists with heat dissipation during high-draw operations. It operates at ≤8W power consumption and weighs ≤300g. The metallic casing shields the internal circuitry from external electromagnetic interference while providing a rugged physical barrier against environmental wear. The pre-drilled mounting holes make it easy to secure to vehicle roofs or drone frames.
Where does the BNTWL100M four-channel GNSS anti-jamming antenna fit best? It is ideal for heavy-duty ground vehicles, maritime vessels, and large-scale unmanned aerial systems. Surveying teams operating in highly congested areas will find the ≥95dB three-jammer resistance crucial for maintaining RTK corrections. Additionally, it is well-suited for stationary reference stations that require uninterrupted uptime in noisy radio environments.
