Abstract : The patent relates to a system for providing lobing only when the system is switched to track operation and then only on receive and not on transmit. The normal track arm is replaced by a short tuning stub which is placed adjacent the output window of the standard trislot transmit-receive tube, so that the trislot reacts on the beam being received through the on-center feed to provide lobing action. A polarization sensitive grid having a plurality of parallel wires is located within the tuning stub. The stub is supported on bearings and is rotatable by means of a lever to switch the grid between the search mode position and the track mode position. An attenuation card is supported on a support plate within the tuning stub.
