A satellite antenna configurable between a closed configuration, so as to be transportable, and an operational configuration, so as to exchange communications via satellite, and comprising: - a case comprising a base and a lid, which is open in the operational configuration; the base and the lid having respective rectangular floor walls (7,8) and respective side walls (9,10), which extend along all the sides of the corresponding floor walls (7,8); the floor wall of said base having an internal surface; - a parabolic dish defined by a plurality of dish portions (24, 25, 26), which are fixed to one another in the operational configuration, are detached from one another in the closed configuration and comprise a bottom central portion having a rear surface and a concave front surface; - a supporting structure fixed to said rear surface; - at least one feeder; - coupling means that couple said supporting structure to an internal portion defining part of said internal surface; said coupling means comprising: a) azimuth-adjustment means for varying the angular position of said supporting structure with respect to said internal portion about a vertical axis in said operational configuration; and b) elevation-adjustment means for varying the angular position of said supporting structure with respect to said internal portion about a horizontal axis in said operational configuration; and - an arm, which carries said feeder and is coupled to said supporting structure in a rotatable way about a further axis parallel to said horizontal axis to be set in an extended position, in the operational configuration, or a folded position, in the closed configuration; in the closed configuration, said bottom central portion being set in a position substantially parallel to said floor wall, as said supporting structure is lowered with a rotation about said horizontal axis when the satellite antenna is configured into the closed configuration starting from the operational configuration; whereby said supporting structure is also rotated through approximately 180° about said vertical axis when the satellite antenna is configured into the closed configuration starting from the operational configuration; characterised in that, in the closed configuration, said rear surface faces said internal surface. - a case comprising a base and a lid, which is open in the operational configuration; the base and the lid having respective rectangular floor walls (7,8) and respective side walls (9,10), which extend along all the sides of the corresponding floor walls (7,8); the floor wall of said base having an internal surface; - a parabolic dish defined by a plurality of dish portions (24, 25, 26), which are fixed to one another in the operational configuration, are detached from one another in the closed configuration and comprise a bottom central portion having a rear surface and a concave front surface; - a supporting structure fixed to said rear surface; - at least one feeder; - coupling means that couple said supporting structure to an internal portion defining part of said internal surface; said coupling means comprising: a) azimuth-adjustment means for varying the angular position of said supporting structure with respect to said internal portion about a vertical axis in said operational configuration; and b) elevation-adjustment means for varying the angular position of said supporting structure with respect to said internal portion about a horizontal axis in said operational configuration; and a) azimuth-adjustment means for varying the angular position of said supporting structure with respect to said internal portion about a vertical axis in said operational configuration; and b) elevation-adjustment means for varying the angular position of said supporting structure with respect to said internal portion about a horizontal axis in said operational configuration; and - an arm, which carries said feeder and is coupled to said supporting structure in a rotatable way about a further axis parallel to said horizontal axis to be set in an extended position, in the operational configuration, or a folded position, in the closed configuration;
