Improved receiving antenna, characterized by comprising a mast with upper crossing and extreme crosspieces to it, in whose crossheads and at the extremities corresponding to the two elements it comprises, projecting, in axial prolongation, dielectric supports that are complemented by other cross-sections with respect to the aforementioned axis, and determinants of plane framings arranged in parallel with respect to the erection of the assembly and whose ends of both framings involve stretched knots of a highly conductive material coated externally of a flexible and dielectric body which in one of the framings determines a closed circuit, while in the opponent, this circuit is open and communicated with the receiving apparatus to be connected, with the particularity that the resistant assembly formed by the mast, the crossing and the crossarms, are established from a tubular material protected from the weather, ferric nature and galva nized, while the supports are of dielectric properties, preferably of synthetic class.
