T.V. reception from transmitting stations located beyond the range commonly covered by T.V. receivers using conventional antennas is achieved by means of a highly directional bi-conical antenna structure that accommodates both VHF and UHF signals. Two truncated conductive cone antenna elements are mechanically connected at their apexes to the ends of an r.f. coil to provide the bi-conical antenna structure. The structure is horizontally positioned and rotatable for alignment with a desired station for optimum reception. A monopole antenna element is center tapped to the r.f. coil and the television UHF antenna lead is connected to the r.f. coil. The VHF antenna lead is connected to the bi-conical antenna structure.
