Abstract : In order to measure aerial characteristics two antennas are required: the airborne antenna, subject to investigation, and the measuring antenna which is normally installed on the ground. Generally, the characteristics of the airborne antenna only must be defined; therefore, the diagram of the ground antenna has to be known, and to be subtracted from the total values. The problems arising with regard to the polarisation of both antennas on account of their geometrical position to each other are shown, and a correction factor is determined which enables the description of the polarisation effect on the energy transmission between radiating antenna and receiving antenna.
