    Ultra enhanced 8-element anti-interference antenna SLA165-8B1L1

    The SLA165-8B1L1 anti-jamming antenna integrates eight B1L1 receiving antennas, an eight-channel RF receiving module, and an anti-jamming processing module, outputting jamming-free RF signals. The antenna can simultaneously resist up to seven suppressive jammers from different directions, fully protecting GNSS satellite signals under strong jamming, meeting the GNSS signal reception requirements of various carriers in complex suppressive jamming electromagnetic environments.

    This antenna integrates the antenna source, RF, anti-jamming module, and upconversion in a compact design, meeting the requirements of high reliability and low cost. Utilizing fully proprietary adaptive nulling antenna and space-time adaptive filtering technology, it significantly improves the availability of GNSS satellite signals in complex electromagnetic environments and offers robust resistance to various types of suppressive interference, including but not limited to single-carrier, swept-frequency, pulse, broadband modulation, sawtooth, triangle, and any combination thereof.
