An antenna comprising a plurality of sections, each section comprising first and second coil forms forming a triangle with a ground plane and having a continuous ribbon cable and a multiconductor cable wound in helical fashion about the coil forms. Selected conductors of the multiconductor cable are terminated at selected sections and connected to PIN switching diodes to switch selected amounts of inductance out of the circuit, thereby providing multiple selectable frequencies of operation for the antenna.
