Low-cost eight-element anti-jamming antenna SLA-8B1L1-110

Low-cost eight-element anti-jamming antenna SLA-8B1L1-110

An Anti-Jamming Antenna is a specialized solution designed to counteract intentional signal interference, ensuring uninterrupted operation of GPS/GNSS navigation and communication systems. By leveraging advanced adaptive nulling and spatial filtering technologies, these antennas detect and suppress jamming signals—including single-tone, swept-frequency, pulsed, and broadband noise—protecting critical positioning, timing, and velocity data.

    Technical Specifications

    SLA-8B1L1-110 Ultra-Compact 8-Element Anti-Jamming Antenna integrates an 8-element B1L array antenna, an 8-channel anti-jamming module, and a high-performance receiver. It supports 8-element B1L1E1 frequency point anti-jamming single-point positioning functionality, meeting the technical requirements of various small carrier applications. It integrates antenna elements, RF channels, anti-jamming processing, and a GNSS receiver within an extremely compact size, fulfilling the needs of high-reliability, low-cost applications. The product is primarily used for real-time output of platform spatial position information, timing, and velocity information, and possesses the capability to resist various types of suppression jamming, including but not limited to single carrier, frequency sweeping, pulse, wideband modulation, sawtooth wave, triangular wave, and their arbitrary combinations.
