In particular, the tests include measurements of beam shape, pointing, gain curves and focus for the different receivers (L, C, X and K-bands). We report the results of the main tests carried out after a long stop of the antenna due to the reparation of the main servo motors chillers in 2020 and compare them with those carried out during the recommissioning in 2018 (after the change of the actuators of the active surface). These results will be useful in order to compare the new status of the antenna after the upgrade of the new receivers at higher frequency (PON).ELETTRONICOenTechnical report
