Abstract :
A technique is described to determine accurately antenna efficiency by comparing integrated isotropic levels of two antennas, one of which is a lossless reference antenna. Standard automated antenna-range instrumentation was utilized to obtain isotropic levels of Apollo scimitar antennas to ± 0.1 dB by reducing or eliminating sources of error due to specular ground reflections as well as results based on a single measurement.
