--- small adjustment of the converter, which conducted the author ---
-unusual converter for offset types of antennas with a small diameter was initially designed to receive waves of
left-circular polarization of the satellite Chinasat 9 at 92.2°E.Author proposed a simple adjustment made
in order to install the converter for PF feedhorn with waveguide flange type C120.But all the measurements and
analysis, I performed only with the dxsatcs waveguide line of third generation .
