The report presents results of mirror surface adjustment on one of largest Russian fully steerable radiotelescopes — 64-meter antenna in space communication center Medvezhy Ozera near Moscow. Radioholographic measurements with 4 GHz satellites signals were fulfilled on this antenna in 1995-96. Restored map of main mirror shows surface deviations near of 2 mm rms. Rms difference of the maps measured under identical external conditions was 0.1 mm. After partial adjustment of mirror surface an antenna efficiency was increased from 0.51 to 0.65 at 5-cm band.
