Electrical transmission tubes, used in short, medium and long waves antennas, play a vital part to power the huge transmitters of a station. At the dawn of the German occupation, an act of resistance prompted to hide the tubes of the long wave antenna in Junglinster in order to hamper the Nazis’ use of the station.

Tubes in Junglinster have been of the most powerful in Europe until the end of the 1960’. Although being mostly replaced at the end of the century, they do resist to today’s technology by playing a minor but vital role in broadcasting.

Throughout generations tubes of different types, shapes, ages and locations have been collected by the employees of the Junglinster site. Although not being part of a state funded museum, the gathered tubes form a little ‘museum’ inside the control room.
