The C-Nav977XF Low Elevation Angle Nulling Antenna (LEANA) is engineered to deliver robust GNSS performance in environments prone to interference. Supporting multiple GNSS constellations and frequencies, the LEANA is purpose-built to suppress jamming signals from near-ground-based transmitters.

Its advanced radiation pattern provides typical wideband suppression of 20 dB for all GNSS band signals received at elevation angles from 0° to approximately 15°. This enables the antenna to operate up to 10 times closer to interference sources than standard antennas—without signal degradation.

Combining low elevation angle nulling with deep filtering and high linearity technologies, the C-Nav977XF LEANA delivers exceptional resilience against RF noise and jamming. It is ideal for mission-critical positioning, navigation, and timing applications.
