(54)	Radio broadcasting system comprising an antenna system, which is constituted by at least a portion of the above-ground component of an electricity distribution network

(57) According to the invention there is provided a broadcast system including a transmitter for transmitting communication signals which transmitter includes a transmitting antenna which is supported on or is constituted by an above-ground component of an electricity distribution and/or power transmission network.
In embodiments of the invention, a part of an existing EDN can take the place of a dedicated transmitting antenna, so avoiding the inconvenience and cost of finding a site for and installing a transmitting antenna.
Support towers (also known as pylons) which serve to support cables in an EDN are typically constructed as a metal space frame. A system embodying the invention can advantageously use such a tower, or part of such a tower, as a radiating element of the transmitting antenna.
