A method for controlling the lengths of length adjustable elements of an antenna includes engaging a motor drive assembly coupled to each length adjustable element and in response to signals from a motor controller for adjusting the length of the length-adjustable antenna elements to element lengths provided by element length tables coupled to the motor controller, running antenna modeling software coupled to the motor controller to generate antenna performance data as a function of antenna element lengths, and driving the motor controller for each motor drive assembly from data in the element length tables to adjust the lengths of the length-adjustable elements in response to commands entered into a user interface or commands generated by the antenna modeling software running in the processor.
