WebAn orthomode transducer ( OMT) is a waveguide component that is commonly referred to as a polarisation duplexer. Orthomode is a contraction of orthoganal mode. Orthomode transducers serve either to combine or to separate two orthogonally polarized microwave signal paths. [1] WebOct 20, 2016 · The minimum gain at zenith of -25 dBi is comparable to that of state of the art 3 kHz channel OTM NVIS antennas. The baseline configuration is a two arm half-loop operating in NVIS mode, designed ... WebThe modified G6 antenna (Figure 1), employs a center-fed horn feed matched appropriately with an OrthoMode Transducer (OMT). It is mechanically steered in both the azimuth and elevation axes. The azimuth range is 720 degrees and the elevation range is 10 to 90 degrees. Figure 1. python123题库
