A comparison of electric field-strength standards for the frequency range of 30-1000 MHz

Published results about site attenuation and transmission loss measurements as well as antenna factor calculations and calibrations are summarized. The antenna types discussed are precision dipoles, a microstrip patch antenna, open-ended waveguides, and horn antennas as well as TEM-cells. The best values for agreement between theory and experiments that were reported for the transmission losses were in the range of 0.25-0.4 dB. An experimental comparison between precision reference dipoles and a TEM-cell that was performed in the Seibersdorf calibration laboratory is described with deviations of no more than 0.15 dB in the antenna factor or field-strength.
