• HA-antennas

    The HA antennas can be used for road and railroad surveys with Rex systems.

  • HA-antennas

    HA antennas can be used for high speed road surveys as well as slower surveys.

Airborne Antennas / HA-series


The airborne HA horn antenna series are an answer to the customer demands for high speed GPR surveys that result in quick data collection and excellent resolutions. By applying advanced design and technology, we made sure that the HA horn antennas are very focused and have low ringing in the upper part of the range, where it matters for their intended applications.

Antennas from the HA-series are used in many different applications, from pavement thickness and road condition assessment, to high speed tunnel surveys with the Rex systems. The HA horn antennas have also been used for road surveys and assessment of primary and secondary lining in tunnels.
