A steerable antenna allows transmission of an electromagnetic signal between a fixed feed source or an image thereof and a target moving within an antenna coverage region. The peak gain of the signal beam varies as a function of the target position following a desired signal gain profile. The antenna includes a reflector defining a reflector surface for reflecting the signal between the feed source or its image and the target. The reflector surface defines a focal point, a center point and a normal axis perpendicular to the reflector surface at the center point. The normal axis and the feed axis intersecting the center point and the feed source or its image define a common offset plane. An elevation rotary actuator rotates the reflector about a rotation axis perpendicular to the offset plane adjacent to the center point so that the antenna provides a nominal signal gain profile over the coverage region. The reflector is shaped to alter the nominal gain profile so that the latter matches the desired gain profile. Preferably, an azimuth rotary actuator rotates the antenna about the feed axis.
