Shortwave Antenna for Ionospheric Satellites

This paper discuss the improvement, proposed by a number of authors, of the performance in the low - frequency part of the sounding range, which is essential for the developed ionosondes with a decrease in the lower frequency of sounding. The ways to compensate for the decrease in the energy potential of the decameter sounding channel in satellite monitoring of the ionosphere from high-apogee orbits by increasing the efficiency of short-wave antennas of satellite ionosondes are considered.
