Abstract: Based on the daily maintenance and overhaul test work of the large-aperture parabolic antenna of the satellite ground station, this paper briefly introduces the maintenance experience of the large-aperture parabolic antenna and the use of the spectrometer to test the antenna pattern, and uses an empirical formula to calculate the gain value of the antenna.

Key words: large-aperture parabolic antenna; maintenance and inspection; antenna pattern; gain calculation
