Pivotable horn antenna for a radar level indicator

A pivotable antenna arrangement for a radar level indicator, comprising:

• an antenna horn;
• a region in a form of a ball joint head attached to the antenna horn;
• and
• a housing having a joint socket, in which the ball joint head can rotate, and which includes a lower region and an upper region that is attachable to the lower region;
• wherein the lower region has an outer diameter, which decreases stepwise towards a lower end of the lower region, with an external thread at the lower end, and a substantially cylindrical recess concentric with the external thread, which is designed for guiding through the antenna before the upper region is attached to the lower region and forms part of the joint socket;
• wherein the recess of the lower region is arranged below the ball joint socket of the lower region;
• wherein the external thread surrounds the antenna horn, which protrudes from the cylindrical recess, and is configured to screw the antenna arrangement into a threaded hole in a container;
• and
• wherein the external thread has a diameter of two inches or less.
