Primary radiator exchange type parabolic antenna and the primary radiator positioning jig

摘要

(57) [summary] [constitute] the primary radiator 2 in the parabolic antenna, It is interchangeably supported on the mounting interface 3, and movably providing the attachment interface 3 in a vertical direction and a longitudinal direction with respect to the reflector 1. In the primary radiator positioning jig 5 with a movable instruction section 5b back and forth to adjust the position of the primary radiator to be interposed between the reflector 1 and the attachment interface. [Effect] It is possible to correspond to the frequency of a wide with a single reflector, it is possible and improve the working efficiency at the time of measurement.
