Abstract
In a satellite broadcast reception converter, probes are equipped in a circular hole formed in a first circuit board, and plural fixing holes are formed around the circular hole. Snap pawls are formed at open ends of the waveguides formed of sheet metal. The respective snap pawls are inserted in the fixing holes of the first circuit board so as to project to the back surface side of the first circuit board, and the fixing holes of the short caps are snapped into the snap pawls. A dielectric feeder of synthetic resin supported on each waveguide has a first split body with radiation portion projected from the open end of each waveguide and a second split body having a phase converter fixed in the waveguide. The first and second split bodies are unified by inserting a projection equipped to the second split body into a through hole formed at the center of the first split body.
