Shop the BNTWL65 4-channel GNSS anti-jamming antenna. Supports BDS_B1, GPS_L1, GAL_E1, ≥110dB single interference resistance, 65x65x20mm compact size, and ≤130g weight.
Signal interference is a major headache in modern navigation. To tackle this, the BNTWL65 four-channel satellite navigation anti-jamming antenna is built to maintain stable positioning even in challenging conditions. This device packs powerful signal processing into a compact, lightweight unit, making it a practical choice for system integrators.
The antenna covers three primary frequency points: BDS_B1, GPS_L1, and GAL_E1. This multi-system approach boosts satellite availability and provides necessary redundancy. If one constellation is blocked or jammed, the receiver can rely on the others. The four-channel configuration is designed to manage multiple signal paths simultaneously, maintaining precise phase alignment and signal strength across the board.
The standout feature of the BNTWL65 is its defensive capability. It delivers an anti-single broadband interference capability of ≥110dB, and an anti-three-broadband interference capability of ≥90dB. For field engineers, this means the unit can filter out strong radio frequency noise and function within congested electromagnetic spectrums without dropping the tracking signal. The hardware-level filtering ensures rapid response times compared to software post-processing.
Physical specifications are critical for tight integrations. Measuring just 65.0mm x 65.0mm x 20.0mm, the device weighs no more than 130g. It also boasts a low power consumption of ≤4W, making it highly suitable for UAVs, portable mapping gear, and vehicle-mounted systems that demand low weight and continuous operation. The metallic housing provides essential shielding for the internal circuitry and aids in heat dissipation during prolonged use.
Where does this anti-jamming antenna truly shine? It excels in areas with high electromagnetic interference, surveying tasks, and real-time tracking of critical assets. For instance, agricultural or surveying drones operating near large structures often face signal degradation. The BNTWL65’s multi-channel design ensures signals are captured and tracked even at low elevation angles. Furthermore, marine and ground mobile platforms use this equipment to mitigate multipath effects. The built-in mounting holes simplify installation on various platforms, allowing users to install and forget without manual parameter tuning.
