A waveguide twist includes at least three waveguide sections which are connected to each other and rotatable about their longitudinal axis usually by a same angle. Each waveguide section with the exception of the first waveguide section and the last waveguide section supports externally a lever which has two axial ends engaging in grooves of adjoining waveguide sections so as to be longitudinally displaceable to allow distribution of the total angle of rotation over the waveguide sections.
