The present disclosure provides an over-the-air measurement system for testing a device under test. The over-the-air measurement system includes an orthomode transducer (OMT) assembly having several separately formed orthomode transducer components that form at least two orthomode transducers. The orthomode transducer assembly has at least two output interfaces for feed antennas. Each of the at least two output interfaces is connected with one dedicated orthomode transducer. Two input interfaces are associated with each of the orthomode transducers. Each of the input interfaces merge into a corresponding waveguide transition that ends up in the respective orthomode transducer that is associated with the corresponding input interface. The several orthomode transducer components are stacked together linearly.

A hollow conductor system is described which comprises at least two hollow conductor bundles and at least two connecting members. Each hollow conductor bundle comprises at least two hollow conductors separated by each other via a common intermediate wall. Each connecting member connects one hollow conductor of one hollow conductor bundle with a corresponding hollow conductor of the other hollow conductor bundle such that a void is provided between the connecting member and the adjacent connecting member and/or an adjacent hollow conductor. Further, a method for assembling a hollow conductor system is described.

Hollow conductor system comprising at least two hollow conductor bundles connected by first and second connecting members and including respective hollow conductor lines and corresponding voids

A switch comprises a first strip conductor and a second strip conductor, arranged orthogonally in a first plane. Moreover, the switch comprises a first switching conductor, having an orthogonally angled shape relative to the first plane. The switch comprises a switching actuator, which is mechanically connected to the first switching conductor and adapted to move vertically relative to the first plane to a first position and to a second position. The switching actuator is configured, so that in the first position, the first strip conductor is in contact with the first switching conductor and the second strip conductor is in contact with the first switching conductor, and so that in the second position, the first strip conductor and the second strip conductor are not in contact with the first switching conductor.
