I have dreamed about remoting my KAT500, but since it won't match my 30' vertical on 80 or 160, I went with a tuner that will do so. It is a remote tuner but not automatic. For a variety of reasons I have it sitting under a "Fake" rock that I got at a big box home improvement center. I think it cost about $28 and protects the tuner from UV and lots of other stuff... PLUS my XYL thinks it looks great compared to the tuner box sitting there. I also have a smaller fake rock over the conduit where it comes up by the tower base... a couple of real rocks (small boulders) helps 'balance' the look at the base of the antenna.
If I recall correctly, AB2TC remotely controls his KAT500. He may weigh in on this discussion. What I recall of his setup is well thought out.
