The invention relates to an aerial (1) for receiving and transmitting radio signals within a certain frequency band. The aerial (1) comprises a radiator element (3) which can radiate a linearly polarized radio signal within the operating band of the aerial. The latter also comprises a support element (2) and at least one first director element (4) mounted on said support element. The director element comprises a body which is conductive within the operating band of the aerial. The shape of said body is such that the projection thereof onto a plane orthogonal to the direction of maximum gain of the aerial encloses a limited plane portion.

摘要:
The present industrial invention concerns a system for the distribution in a condominium and/or community environment of a plurality of television signals, and/or audio signals, and/or digital audio and/or video signals transmitted with different standards. According to the invention, one or more digital signals can be received by a single user of the system by means of a frequency conversion into a predetermined channel, which can be accessed by said user only. Moreover, the digital signal being present in said channel always has the same modulation and can be selected by said user through control means which send a control signal to selection means.
