Abstract

The orthomode transducer (OMT) has a motor or hand driven (23) polarising section with susceptive depolarising elements (26) which can be rotated to convert circular input polarisations to linear polarisation at the two waveguide output ports (6,10) or to allow linear polarisation to pass unchanged.
