20dB attenuation at 0-15° Elevation
AJ977XF Key Applications
Mission-critical global positioning
Timing applications
Law enforcement and public safety
Purpose-Built to Block Interference
With Low Elevation Angle Nulling Antenna (LEANA) technology, the AJ977XF suppresses up to 20 dB of jamming signals from low elevation angles. Combined with a 15 dBm OP1dB compression point, it prevents LNA saturation, ensuring GNSS receivers remain functional under heavy interference.
Robust Signal Integrity
Integrated eXtended Filtering (XF) technology provides deep filtering and high IP3 performance to block unwanted signals before they reach the receiver. This ensures dependable accuracy across all major constellations and SBAS systems, including GPS, GLONASS, Galileo, BeiDou, WAAS, EGNOS, MSAS, and GAGAN.
Reliable Navigation, Anywhere
Whether deployed on aerial, maritime, or ground-based platforms, the AJ977XF ensures mission-critical navigation data stays accurate and protected, delivering unmatched resilience against today’s rising interference threats.
