A feeder horn intended particularly for two-way satellite communications equipment and including a central transceiver horn (10) and at least three separate measuring horns (11, 12, 13) placed symmetrically in relation to the feeder horn symmetry line (O), wherein all horns are produced mechanically in one and the same metal element (1) which includes a through-penetrating centre opening (100) for the transceiver horn (10), a bottom-delimited opening (110, 130, 140) for each of the measuring horns (11, 12, 13), and a moat-like recess (104, 114, 124, 134) in the metal element (1) around each opening (100, 110, 120, 130) for insulating each horn electromagnetically in relation to other horns. The delimited opening (110, 120, 130) for each of the measuring horns in the metal element (1) is filled with dielectric material (1101, 1201, 1301). An adaptation lens (2) which includes a centre hole (20) that is adapted to the centre opening (100) of the transceiver horn (10) is arranged in front of the metal element (1).
