In each of the shallow trenches on the LBA field, there are white agricultural drains, which we use as ducting for the cables. Because we have rocky, unforgiving soil, and the fact that it freezes up each winter, means that we need to provide additional protection for the cables that we have. This is in contrast to other LOFAR stations, where the cables are buried directly into the ground.

mausoleum. As the ducts get closer to the RF-container, there are
more and more cables in each. This is why the duct diameters
in this location is larger. (Photo: D. McKay-Bukowski) |
