Back last year when i was having trouble getting my BUD aligned to the arc to get both C and Ku, before I finally gave up and replaced the C/Ku with C only I thought it would have been much easier if my dish could move in Az and El so I could find each satellite like I would locate a Ku sat with a dedicated dish, you know right, left, up, down until zeroed in, and be able to find and save the optimum position for C and Ku separately, as well as polarity for each.

I found this site http://www.fibo-box.com/ a couple of years ago, it looks very interesting. Has anyone here seen this before or used one of these?
 
Never used that controller, many others have used various others though. I built a simple unit to control my actuator using an Arduino and L298N.

a true Ez/El will need a servo polarity control (or some other method to skew the lnb). Many that you see floating around the internet are not true ez/el and just have a small actuator on the elevation screw of an H-H mount. That type of mount will adjust the elevation at true south and only the skew at the edges of the arc near the horizon.

Yaesu builds some nice Az/El units that work for ham arrays. Also Alpha Radio in Edmonton builds these:

Of course dish and custom mount/counterwight not included..
I think these units resolve to about 1/10 degree, and likely the sensors could be modified for higher counts/deg.

An equatorial mount with a servo of some kind for declination adjustment would work best for Clarke belt satellites, unless you are interested in tracking non-geosynchronous satellites.

Dish and LNB for receiver ?
