Another low frequency array in the Netherlands

This low frequency antenna array operates at 16.10 to 16.25 MHz, but it is not related to Lofar or Astron, and not even to radio astronomy. It is owned by Rijkswaterstaat, the Dutch department of water management. I ran into it when camping near Ouddorp in Zeeland (NL).

The antenna array is located in the dunes, and points at the North Sea off Hook of Holland. It has a counterpart about 30 km to the North, at the other side of the port entrance. At both sites, 4 antennes transmit and 12 receive. Together they form a radar system that measures the sea currents. This information is used by the ships to safely enter the port of Rotterdam.
