Abstract : A deployable antenna assembly includes a canister providing an elongated chamber and an elongated hollow mast with a mounting member on its upper end. A coaxial cable extends into the hollow mast to provide radio signals to the antenna assembly and four antenna members of resiliently deflectable wire spaced at 90o intervals about the periphery of the mounting plate comprise a generally helical coil and elongate arms extending downwardly along the inner wall of the canister, and each opposed pair comprises a dipoles. A pair of baluns are connected to the coaxial cable and disposed adjacent the mounting member, and a phase shifter is connected between the coaxial cable and one of the baluns. Connectors conductively connect the central conductor of the balun to the coil of one of the antenna members of a dipole, and the conductive shield to the coil of the other antenna member of a dipole.
