Radar Wind Profiler LAP®3000

LAP®3000 - Standard Antenna

This is the standard model of the LAP®3000 Radar Wind Profilers for reliable and continuous wind measurements up to a height of 4 km above the ground with proven performance. The integrated clutter screen yields optimum ground-clutter suppression and ensures safety by shielding the RF radiation. Multiple radio-frequency variants are available for use in different frequency allocation regions worldwide.
