Disclosed is a shaped horn in conjunction with a dielectric tube for enhanced aperture directivity that can achieve a near optimum efficiency. The shaped horn provides additional mode control to provide an improved off-axis cross-polarization response. The horn shape can be individually optimized for isolated horns or for horns in a feed array. The feed array environment can produce results that lead to a different optimized shape than the isolated horn. Lower off axis cross-polarization can result in improved efficiency and susceptibility to interference.

Systems, methods, devices and apparatus are disclosed that include a chassis mount adapted to be attached to a vehicle and an antenna mount adapted to receive a satellite antenna. Further, the systems, methods, devices and apparatus that include a gyroscopic stabilizer attached to the antenna mount configured to convert vibrational torque applied to the antenna mount into a linear displacement of the antenna mount using one or more gyroscopes, each gyroscope having a control moment. In addition, the systems, methods, devices and apparatus that include a linear displacement spring attachment device connecting the antenna mount to the chassis mount and configured to provide a restoring force in opposition to the linear displacement.
