Abstract
Uncertainty estimation in any measurement is an involved process. As an idea towards simplifying this process in respect of the gain measurement and secondary calibration of antennas, in this article, a modified three-antenna measurement method is suggested. This method may be particularly effective when the reference antenna is chosen so that its gain is comparable with that of the test antennas. As an illustration, the gain measurement of an E-plane sectoral horn is considered.
