Radiation characteristics of the offset paraboloidal reflectors illunminated by a tilted prime-focus feed are studied employing the physical optics current method. A family of curves is generated which indicates the optimum orientation of the axis Of the feed for maximum antenna efficiency as a function of the offset angle
