Abstract (en)
A transmitter network comprising a plurality of transmitters having a like transmitter frequency may cause disturbance to occur in an adjacent similar transmitter network. This disturbance is no longer of an echo signal type, so that cancellation thereof will be more difficult. For eliminating this disturbance as much as possible, a transmitter network is proposed in which auxiliary transmitters are used having an aerial height which becomes smaller according as the edge of the coverage area is approached more.
