    Abstract: A radio antenna which takes the form of a flexible elongated transmission cable. This cable encloses a pair of conductors which are insulated from each other. The cable is encased in an electrically conductive sheath. The received signal is picked up by the sheath and transmitted through an impedance matching network and into the pair of conductors. The length of the sheath is correlated to a preselected fractional value of the wavelength of the received signal.
