OMEGA La Reunion Antenna System: Modification and Validation Tests. Volume 1. Report Proper.

Abstract

Electronic measurements were performed on the La Reunion Omega Antenna System during the month of August 1978. The work was performed under NOSC project MP01538B10, with Megatek Corporation as contractor. The necessary connections to the antenna helix tuning coil were completed so that the station can now operate on 11.050 kHz. The total antenna system resistance was measured and found to compare favorably with original measurements made in 1975. An analysis was made of optimum gear ratios to use with the variometers used to keep the antenna system tuned. The electrical height of the antenna was found to be 163 metres for 10.2 kHz and to increase slightly with frequency to 170 metres at 13.6 kHz. The antenna system efficiency varies with frequency from 8% to 13.8%. The station can easily radiate the designed 10 kW power. (Author)
