Abstract :
The results are presented of an international comparison of measurements of the complex reflection coefficient in the G 900-14 mm/50 ohm coaxial line at 0.5 GHz, 3 GHz and 7 GHz in which eleven national laboratories of metrology participated. The standards showed very small drifts of the reflection coefficient during a period of nine years. With few exceptions, good agreement between the mean values reported by the different participants is observed.<>
