Arrays of Beverage antennas

A summary of the research performed on Arrays of Beverage Antennas is presented. It begins with a discussion of the theoretical and experimental determination of the circuit and radiating properties of single horizontal-wire antennas over an imperfectly conducting half-space. This study was reported earlier, in detail, in Scientific Reports Nos. 1 (Vols. 1 and 2) and 2. The antennas are either loaded with a resistor and a quarter-wave section of line to form the modified Beverage antenna or are open-ended. King:s theory for the unloaded antenna is extended to apply to the terminated Beverage antenna. Measurements made on both types of horizontal antenna when placed at varying heights above fresh water, salt water and moist earth are compared with theory. A similar study of the circuit properties of coupled parallel horizontal-wire antennas above an electrically dense dissipative half-space is then reported.
