In this paper we discuss the results of an intercomparison for free spaceantenna factor measurements performed within the German Calibration Service(DKD). Three different types of antennas covering the frequency range from30 MHz to 26.5 GHz have been calibrated in five different laboratories usingdifferent methods and calibration sites to obtain the free space antennafactor. The results agree well within the uncertainties specified by thelaboratories suggesting that different approaches and different measurementsites to obtain the free space antenna factor are well compatible
