An orthogonal mode transducer including: an elongated waveguide conduit for projecting orthogonal polarisation transmissions, the conduit having a proximal emission source end and a distal mouth end having an aperture for signal transmission; and the elongated conduit including a first and a second pairs of diametrically opposed axial ridges, with the first and second pairs being substantially orthogonal to one another, and the first pair of diametrically opposed axial ridges having an asymmetric narrowing of the gap between the ridges towards the proximal emission source relative to the second pair of diametrically opposed axial ridges. The axial ridge increases in circumferential thickness towards the distal end of the conduit. The asymmetric narrowing is provisioned substantially at the proximal emission source end only with the gap between the first pair and the second pair of ridges being substantially the same at the distal mouth end of the conduit. |
