The 100‐kW transportable very low frequency transmitter system was used at Kafjord, Norway, for transmissions to the SCATHA and GEOS spacecraft. A 22‐kV, 10.6‐km long transmission line was used as an antenna. Modifications were made in the line to reduce telephone interference. Components were designed and installed to reduce the resonant frequency and increase the antenna current. The final practical operating current was 45 A at 1280 Hz. This resulted in power dissipation of 72 kW and an estimated radiated power of 0.17 to 0.79 W.
