Abstract: Continously variable-length antenna, operating in a wide frequency range that's simple, lightweight and reliable, and can be constructed by using a metal case-resided, coiled steel band spring returnable metal tape for the actual antenna, and pulling or releasing it by a thin insulating line. A strong, lightweight insulating tube, guiding the metal tape in its mechanical excursions, also provides for weatherproof construction. Remote controlling and an extremely wide range of antenna lengths can easily be realized.
