L-IESA® Mini Antenna

Smart IFF solution for ships

Get to know the L-IESA® Mini, an advanced IFF transponder antenna designed for naval ships. It ensures seamless identification by eliminating signal interference caused by ship structures, providing clear and uninterrupted coverage.

Why L-IESA® Mini Antenna?

Traditional ship antennas send signals in all directions (360°) to ensure identification. However, large structures on ships, such as masts and walls, can reflect these signals, leading to self-interference. This interference creates deep coverage gaps in the antenna pattern (visible in the red curve of the test diagram) where the ship might not be identifiable.

These gaps can pose serious risks in military operations, potentially leading to misidentification, communication failure, or non-compliance with strict NATO standards.

A common workaround is installing two antennas on opposite sides of the ship, but this still leads to signal reflections and weak spots in coverage, making them non-compliant with strict NATO standards.

Key advantages

The L-IESA® Mini antenna offers the following key advantages:

  • Directional coverage
    Unlike traditional omnidirectional antennas, the L-IESA® Mini radiates signals outward (200°), avoiding reflections from the ship itself.
  • No self-interference
    Its built-in rear reflector ensures that signals are not obstructed by ship structures.
  • Meets NATO standards
    The antenna is conform IFF Mode 5 standards (AEtP 12.3), ensuring compliance.
  • Improved identification
    By eliminating weak spots, ships remain identifiable at all times, from all directions.
  • Flexible installation
    Can be mounted directly on the ship’s outriggers, or on existing omni-antenna holders.
