The absolute gain of wide-beam antennas may be accurately measured using the method described. Both the theoretical and practical aspects of gain calibration on a ground reflection antenna range are presented. The measurement procedures developed were used to calibrate a log-periodic antenna at selected frequencies from 250 to 400 MHz. Measured data at 300 MHz is tabulated and error contributions are analyzed, yielding a measurement accuracy of ±0.27 dB with a 95 percent confidence interval.
