Abstract :
On VHF earth-space links near the geomagnetic equator, the sense of rotation of circularly polarized waves may, under some conditions, be reversed when penetrating the ionosphere. More generally, circular polarization is deformed to elliptical polarization. The effect may cause large, unexpected fades on links with circularly polarized terminals.
