Abstract :
When one considers the losses in an antenna impedance measurement of the Very-low Frequency RPI experiment in space mostly caused by local electrons and ions flowing into the antenna and the spacecraft, instead of radiation, because these losses were non-linear with voltage, and can explain the excellent recordings of multi-bounce whistler mode echoes as self-focused in spite of low power, the search for new antenna configurations is required if high-power transmission is necessary. Understanding the antenna in plasma as a real transmission line, leads to a magnetic-electric antenna, end-loaded with capacity.
