摘要： An antenna system comprises an antenna feed support and a driver. The antenna feed support is configured to mount a circularly polarized antenna feed to an antenna dish to extend outward along a longitudinal axis of the circularly polarized antenna feed with respect to a reflective surface of the antenna dish. The driver is configured to rotate the circularly polarized antenna feed to adjust alignment between the circularly polarized antenna feed and a remote antenna. The driver can rotate the circularly polarized antenna feed mechanically, electrically or both to adjust alignment between the circularly polarized antenna feed and a remote antenna to reduce cross-pol discrimination at the circularly polarized antenna feed.
