An orthomode transducer (OMT) is a waveguide component that is commonly referred to as a polarisation duplexer. Orthomode is a contraction of orthogonal mode . Orthomode transducers serve either to combine or to separate two orthogonally polarized microwave signal paths. [ 1 ]
Most hydrographic operations use a 200 kHz transducer, which is suitable for inshore work up to 100 metres in depth. Deeper water requires a lower frequency transducer as the acoustic signal of lower frequencies is less susceptible to attenuation in the water column. Commonly used frequencies for deep water sounding are 33 kHz and 24 kHz.
Astra type LNBFs incorporate two probes in the waveguide, at right angles to one another so that, once the LNB has been skewed in its mount to match the local polarization angle, one probe collects horizontal signals and the other vertical, and an electronic switch (controlled by the voltage of the LNB's power supply from the receiver: 13 V for ...

Vertical transom and stern of a modern cargo ship. In some boats and ships, a transom is the aft transverse surface of the hull that forms the stern of a vessel. Historically, they are a development from the canoe stern (or "double-ender") wherein which both bow and stern are pointed. Transoms add both strength and width to the stern.
