A detailed description is given of the experimental and theoretical results obtained from a study of the Beverage antenna. The results show that this antenna is useful as a receiving antenna in the high frequency range because it is highly directive, largely frequency independent, has a low take- off angle and is relatively inexpensive to construct. Since the electrical properties of the ground over which HF antennas may be situated will affect their performance, a novel technique is described, which utilizes a single Beverage element to determine these properties. Comprehensive Beverage antenna engineering-design-data have been calculated and tabulated in a readily accessible format for the communications engineer. Beverage antennas are shown to be effective elements or building blocks for HF antenna systems, such as rosette and linear antenna arrays.
