(under subclass 700) Subject matter wherein the active antenna is combined with conductive (usually metallic) structure, (e.g., a rod) which reradiates into free space impinging radio waves coming from or going to the active antenna, the velocity of the reradiated wave having a component in the direction of velocity of the impinging wave, thereby to modify the radiation pattern of the active antenna, there being no significant potential relationship between the active antenna and the conductive structure.
