Abstract
A rotatable antenna is disclosed in which a radiator and matching network comprise a contiguous electrically conductive spring wire. The matching network comprises a coil extending generally perpendicular to the radiator. A 50 ohm coaxial cable has its ground conductor electrically connected to an electrically conductive sleeve which overlies the coil while the main conductor of the coaxial cable is tapped to the coil so that the matching network substantially matches the radiator impedance to the transmission line impedance. The matching network is rotatable with respect to a mounting member so that the radiator becomes rotatable about an axis that is generally perpendicular to the radiator.
