Working standard for verification of measuring antennas P1-139/1

P1-139/1 working standard for the verification of measuring antennas in the frequency range 3.95 - 5.85 GHz.
Working standard for verification of measuring antennas 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 P1-139/1 is based on the conversion of the electromagnetic field energy flux density into the corresponding high-frequency power in the path. Structurally working standards P1-139/1 are pyramidal horns, having the form of a truncated pyramid with a rectangular base and top, with connecting flanges of WR-187 standard (cross-section 47,55×22,15 mm). Recommended for verification of measuring antennas 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.
