Abstract :
A new quad-ridged, flared horn achieving nearly constant beamwidth and excellent return loss over a 6:1 frequency bandwidth is described. The system performance in two Radio Telescopes: 1) A 12-meter symmetric dual shaped reflector system intended for geodetic very long baseline interferometry and 2) A 15-meter offset dual shaped reflector intended for the SKA is presented showing it to be excellent wideband feed choice.
