Shushi-Wan Omega Transmitter (station H) situated near Shushi-Wan on Tsushima Island at used as its antenna a 389-metre tall tubular steel mast, insulated against ground. This mast, which was built in 1973 and which was the tallest structure in Japan (and perhaps the tallest tubular steel mast ever built) was dismantled in 1998 by crane.
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 ]
Some naturally occurring structures can also act as waveguides. The SOFAR channel layer in the ocean can guide the sound of whale song across enormous distances. [2] Any shape of cross section of waveguide can support EM waves. Irregular shapes are difficult to analyse. Commonly used waveguides are rectangular and circular in shape.
IEEE 1451 is a set of smart transducer interface standards developed by the Institute of Electrical and Electronics Engineers (IEEE) Instrumentation and Measurement Society's Sensor Technology Technical Committee describing a set of open, common, network-independent communication interfaces for connecting transducers (sensors or actuators) to microprocessors, instrumentation systems, and ...

At frequencies of microwave and higher, power losses in transmission lines become excessive, and waveguides are used instead, [1] which function as "pipes" to confine and guide the electromagnetic waves. [6] Some sources define waveguides as a type of transmission line; [6] however, this article will not include them.
A NAVTEX receiver prints an incoming message NAVTEX message for the Baltic Sea. NAVTEX (NAVigational TEleX), sometimes styled Navtex or NavTex, is an international automated medium frequency direct-printing service for delivery of navigational and meteorological warnings and forecasts, as well as urgent maritime safety information (MSI) to ships.
