You can use nearly any antenna rotator with the boxes, but you will need a serial rotor interface. They are not very easy to find, most manufacturers are using parallel port or usb. By far the best interface is produced in germany, see
www.schmidt-alba.de, built one of these and they are running fine. This interface supports a lot of different rotators, even azimuth/elevation models are supported, documentation and support by the manufacturer are outstanding.
