Working standard for verification of measuring antennas P1-139/4

P1-139/4 working standard for verification of measuring antennas in the frequency range 12,4 - 18,0 GHz. Working standards for verification of measuring antennas P1- 139/4 together with measuring and computing complexes and installations are used for verification of antennas and measurements of Ku (effective area) of antenna devices. The principle of operation of working standards P1-139/4 is based on the conversion of the electromagnetic field energy flux density into the corresponding high-frequency power in the path. Structurally, working standards P1-139/4 are pyramidal horns having the form of a truncated pyramid with a rectangular base and top, with connecting flanges of WR-62 standard (cross-section 15,799×7,899 mm). Recommended for measuring antennas verification and antenna measurements. It is ideal for use as a part of measuring complexes for carrying out radio measurements on the basis of compact polygons: near zone; far zone on the basis of BEC; collimator type.
