Thank you for visiting Portable Rotation’s web site. We strive to provide quality products for use by the Amateur Radio Operator or other communications professionals that needs a light weight 12 volt Portable Rotor System. Portable Rotation was created to fill a need for the portable operators that use directional antennas and need an easy way to rotate their antennas. Our original product, the Ultra-Portable Rotor System was designed to turn an antenna as large as the Super Antennas YP-3 3-element Yagi antenna. Since then we have been developing new and exciting antenna aiming and support products including an all weather single axis Rotor and a Dual Axis Rotor System for satellite tracking.
