Abstract:

Described is a vehicular mounted loop antenna which operates as an NVIS radio communication antenna over one range of frequencies and as a vertically polarized whip antenna over another range of frequencies corresponding to the frequency range of a radio communication set equipped with a conventional whip antenna. A coupling loop of variable area and a transmitting loop are positioned in a common vertical plane on a horizontally disposed base member, with the coupling loop positioned within the transmitting loop. A variable capacitor is in circuit with, and is an integral element of, the transmitter loop to provide resonance over the desired operating frequency range. Author
