Device for mounting and removing the source of an antenna on a reflector of this antenna, the source including an electromagnetic excitation assembly situated at the end of an assembly for guiding the electromagnetic waves, the device comprising: - a support for the source traversed by the guidance assembly in such a way that the excitation assembly is turned towards the concave face, called front face, of the reflector when the support has been installed in an aperture formed for this purpose in the reflector, - intermediate means for fixing the support, equipped with the source, onto the reflector, the intermediate means being fixed onto the convex face, called rear face, of the reflector, - means for radio frequency matching of the source to the reflector, centred on the reflector and situated on its concave face, characterised in that the intermediate means (7) are arranged to be fixed onto the rear face (8) of the reflector (9), in order to accommodate the support (4) coming through the front face (11) and to be removed with the support (4) through the rear face (8). Such a device may particularly be used on the reflector of a parabolic antenna. <IMAGE>
