ABSTRACT:
A horn type microwave antenna includes a main reflector and sub-reflector that are supported in proper spaced relationship by flexidigit robotic manipulators, multisection arms that are capable of positional changes, whereby the supports may be changed in position responsive to the application of control voltages. At least a portion of the manipulators include piezo electric actuators, permitting rapid adjustment of the reflectors' position.
