In the process of development of mobile telecommunication systems a specific aggregate, namely, an antenna post, has been constructed. The antenna post comprises feed, receive-transmit, control, life supporting, guidance and energy supply subsystems. Depending on purpose tasks the number of subsystems is changed.

Ternopil State Design Office "Promin" in cooperation with the Laboratory of Antennas and Telecommunications of the National Technical University of Ukraine "KPI" have created and tested antenna posts for earth stations of different types in C- and Ku- band.

The design is based on a modified dual reflector Cassegrain antenna. To meet the INTEL-SAT/EUTELSAT requirements concerning with radiation patterns at a principal and cross polarization the synthesis of amplitude and phase field distribution at aperture of the main reflector has been realized.
