The ATU version 2 works really well as does the actuator controlling the whole antenna.
I am just using the manual keypad as my CAT port is already occupied with a cable feeding the PC.
The Ciro Mazzoni serial switch port splitter is expensive but may be a future purchase if it works ok with Ham Radio Deluxe etc.
The antenna and associated equipment are extremely well made, came in an enormous cardboard box which was well padded and should last a few years.
