Abstract:
A gimbal structure for supporting an antenna having a circular dish and driving said antenna in azimuth and elevation comprising:a hoop structure having a curvature and central axis which is substantially the same as that of the circular antenna dish, means for pivotally supporting said dish on said hoop structure at opposing points on both said dish and said hoop structure, means for driving said hoop structure and said antenna dish along with said hoop structure about said central axis between a first position whereat the Y axis of the antenna dish is in a predetermined â€œzeroâ€  position and a second position whereat the Y axis of the antenna dish is in a position between zero and ninety degrees degrees from said â€œzeroâ€  position, and means for pivotally driving said dish, whereby when said dish is in said first position said antenna dish is pivotally driven in elevation and when said dish is in said second position, said antenna is driven in azimuth or a combination of azimuth and elevation.
