halves being arranged and/or held above a mount in front of an electrically conducting reflector, the mount comprising for each polarisation two mount halves, which are separated by a slot running therebetween, which extends between the two mount halves over the full height of the dipole-type radiator or as far as a connecting link formed on the mount base and connecting the two mount halves, the two radiator halves being fed via an unbalanced two-line system comprising a ground line and a signal line, in which system the ground line is coupled galvanically or capacitively in the region of a first radiator half or mount half to this radiator half or mount half, and the signal line is taken across the slot to the second radiator half, which is opposite the first radiator half or mount half, and coupled there galvanically or capacitively to this radiator half, a second two-line feed system provided for the at least one polarisation plane, the second two-line feed system likewise
