Standard-Site Method for Determining Antenna Factors

A method for calibrating antennas from site attenuation measurements made on an open-field site is described. The method, termed the standard-site method because the accuracy of the results depends on the quality of the measuring site, requires neitller the use of a standard antenna nor the generation of a standard field. The antenna factors of a number of broad-band antennas calibrated by the standard-site method over the frequency range 30-1000 MHz show good agreement with the antenna factors found by the standard-antenna method.
