AJ977XF Anti Jam antenna is designed to mitigate interference and jamming signals broadcast from near ground-based transmitters. The radiation pattern of the Low Elevation Angle Nulling Antenna (LEANA) provides 20 dB (Typical) wideband suppression for all GNSS band signals received at an elevation angle of 0° through to approximately 15°. This level of attenuation will mitigate a 600 Watt jamming signal broadcast at an elevation angle of 10°, 100m or greater away from the AJ977XF antenna.
Tallysmans AJ977XF antenna is ideal for all mission critical positioning, navigation and timing applications.
