Low Elevation Angle Nulling Antenna (LEANA)

The C-Nav979XF+-MAR Low Elevation Angle Nulling Antenna (LEANA) is designed to deliver reliable GNSS performance in environments prone to interference. Supporting multiple GNSS constellations and frequencies, it mitigates jamming signals from low elevation sources near ground and marine-based transmitters.

Its advanced radiation pattern provides typical wideband suppression of 20 dB for GNSS signals received between 0 degrees and approximately 15 degrees elevation, enabling operation significantly closer to interference sources without signal degradation. Combining low elevation angle nulling with deep filtering and high linearity technologies, this antenna delivers robust resilience against RF noise and out-of-band interference.

  • Multi-constellation decimeter performance
  • Suppression of all in band signals below 15-degree elevation 
  • Not export controlled
