ou seek has already been done.  AMSAT sells the boards and a programmed microcontroller for an AZ/EL rotor using servo motors.  It is very robust and can take directions directly from SATPC32.  I built mine and love it.

As I understand, servos primarily rotate 180 degrees left or right governed by the control signal.  That would accomplish the above requirements of pointing the antenna and adjusting for optimal signal.

However, and a BIG however, I know zip about servos or controlling them.  I realize too that their would be a antenna weight problem to overcome and other mechanical factors too!

Consequently, I am wondering it any of you experienced operators have contemplated this before?
