Beverage antennas for HF communications, direction finding and over-the-horizon radars / by J. Litva and B.J. Rook. : Co24-3/7-1282-1976E-PDF
"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. These have application to HF direction finding, over-the-horizon radar and point-to-point communication systems. It is shown that a Beverage linear array system has sufficient gain at high frequency that it may be used in the transmitting as well as the receiving mode. A listing of a computer program is included which can be used to calculate all necessary design parameters of either single Beverage antennas or arrays of Beverage antennas"--Abstract, page 1.
