The invention relates to an antenna intended for the receiving of waves in the myriametre to decameter and even metre bands. The antenna comprises an aerial (A) of the inverted-cone type, placed at altitude relative to the ground and coupled to the receivers (R, R') to be fed by as many channels made from passive elements as receivers; each channel comprises its filtering cell (L1-C1, L2-C2), its impedance-matching circuit (T1, T2) for the coupling with the receiver (R, R') and possibly a resistor (R1, R2) serving in particular to regulate, to an optimal reception level, the signal furnished to the receiver. Application to wideband receiving antennas. <IMAGE> |
