The utility model discloses a satellite signal reception module and vehicle-mounted satellite antenna. The satellite signal reception module comprises a front cover, a rear cover and a high frequency head. Part of the structure of the high frequency head is located in a cavity formed by the front cover and the rear cover. A hole for passing of a corresponding section of the high frequency head is arranged in the rear cover. A sealing ring is arranged at the gap between the hole and the high frequency head. The high frequency head and the sealing ring are in interference fit and can rotate relatively. The sealing performance of the vehicle-mounted satellite antenna is raised, and therefore the service life is prolonged and the reliability is raised.
