Dual band antenna array (Small Size)

  • Dual-band multi constellation anti-jamming phase antenna array
  • Dual-frequency solution: L1 / L2 / L5 can be used (consider specified options)
  • 4 receive channels for each frequency band
  • Dual-band protection combined with AJ2.x (AJ2.x-OEM) Anti-Jamming GNSS receiver
  • Easy to integrate, ideal for retrofitting


This is 4-elements Phased Array Antenna with frequency filtering at the antenna inputs and LNA on-board. The Anti-Jamming function is achieved by using it combined with Kosminis Vytis Anti-Jamming GNSS receiver which includes an Anti-Jamming GNSS processor. Signals acquired by Array Antenna are digitized and processed with KV-AJ2.x (KV-AJ2.x-OEM) high dynamic range receiver after which the navigation signals or solution is resistant to jammers.

A 4-element antenna array as part of the KV-AJ2 Anti-Jamming GNSS system allow gain pattern shapes to be changed in response to interference. Provides up to 3 independent nulls.
