An antenna assembly may include a radome over the linear assembly. A linear assembly may include three or more antenna sections, each with a trough-like reflector formed by two parallel walls, and may have corrugations at the outer edges to reduce noise. An array of radiators may be positioned at the base of each antenna section. The antenna sections may share a common vertical axis and each may have a beam axes that is offset by an angle. Adjacent antenna sections may be separated by an isolation plate with a corrugated outer edge. Each antenna section may radiate greater power in a specific direction as compared to the other antenna sections. ## Claims ### Claim 1 An antenna assembly having a first vertical axis, the antenna
