Abstract :
A compact L band antenna feed system is needed for use on 25m cassegrain radio telescopes. A horn fed lens antenna has been designed using CAD, and a scale model constructed. A mounting and positioning system has been devised for the full-size feed system. Results oftests on the model have been encouraging, and the initial computer model has been improved.
