Kafjord, Norway Transmission Line VLF Antenna Tests, 1979-1980.

Abstract

The 100-kW Transportable Very-Low-Frequency (TVLF) system was used at Kafjord, Norway, for transmissions to the SCATHA and GEOS spacecraft. A 22-kV 14-km long transmission line was used as an antenna. Modifications were made in the line to reduce telephone interference, and components were designed and installed to reduce the resonant frequency and increase the antenna current. Final practical operating current was 40 amperes at 1280 Hz, which resulted in power dissipation of 72 kW and an estimated radiated power of 29 watts. (Author)
