Rubber Ducky Antenna

The rubber ducky antenna (or rubber duck aerial) is an electrically short monopole antenna which functions somewhat like a base-loaded whip antenna and is sealed in a rubber or plastic jacket to protect the antenna. Electrically short antennas are often used in portable equipment because a one-quarter wavelength element, necessary for resonance of a linear element over a ground-plane, is often too long for convenient portable operation. Many years after its invention in 1958, the rubber ducky antenna became the antenna of choice for many portable radio devices, including walkie-talkies and other portable transceivers, scanners, GPS receivers, and any other device where safety and robustness take precedence over antenna capabilities.

Famous quotes containing the word rubber:

    Time for the flat-headed man. I recognize that listener,
    Him with the platitudes and rubber doughnuts,
    Melting at the knees, a varicose horror.
    Hello, hello. My nerves knew you, dear boy.
    Have you come to unhinge my shadow?
    Theodore Roethke (1908–1963)
