Abstract (en)
An antenna diplexer of an uncalibrated metal diaphragm type, comprising an outer casing (2) made of a metal conductive material therewithin is arranged a metal reed element longitudinally extending with respect to said diplexer and thereon are formed a plurality of diaphragm elements (6) defining resonating cavities (7) therebetween, on said casing (2) being moreover provided signal input/output guides (8, 9) and a T-shape joint (5), characterized in that the first/last resonating cavity (7a) is formed at said input/output guide (8, 9).
