Australian Amateur Radio STation



9cm CP feed for EME



The dish feed is a square septum feed with a transition to a round septum and a choke flange to improve dish illumination. It is a scaled version of "RA3AQ's" feed that was optimised for 1296 to feed dishes with f/d of 0.39 - 0.45. The feed was built out of 0.5mm copper sheet and the septum is seam soldered into position.
