AJ977XF+ | Anti-jamming triple band Calian antenna
The AJ977XF+ is a multi-constellation, triple-band (L1/L2/L5) GNSS antenna designed for operation in challenging environments where interference such as jamming or spoofing may originate from ground-based sources.
Thanks to its embedded LEANA (Low Elevation Angle Nulling Antenna) technology, the antenna provides 20 dB wideband suppression for all GNSS band signales received at an elevation angles between 0° and 15°.
The antenna also integrates the “eXtended Filtering +” technology, featuring two separated filtering stages: one dedicated to the upper bands (L1/L2) and one to the lower band (L5). This isolation improves robustness by preventing interference or saturation on one band from affecting the others.
The AJ977XF+ includes a through-hole connector and does not require a ground plane.
