OK, here they are......
Pics should be somewhat self-explanatory.
The round plate with the yellow sticker is the the base plate from the optional three legged stand that Winegard sells for the Carryout.
Included legs not used; instead I made 3 shorter "legs" to support the base plate about 1.5 inches off the roof.
Fourth picture shows how the support legs were fabricated from two L-shaped galvanized pieces of sheet metal. Got six of them at Home Depot and hack sawed about an inch off one side of each. This was to shorten the height of the finished bracket down the 1.5 inches; otherwise the the whole thing would have been 2.5 inches above the roof.
Notice the four black rubber feet on the bottom of the CarryOut. I had to add a couple of washers as shims to each one of them. The screws I used to mount the legs to the base plate were just high enough that the four rubber feet would not drop into the slots in the base plate of the stand.
After shimming, just set the CarryOut on the base plate so the 4 feet line up with the "key holes" in the base plate and twist the CO counterclockwise a few degrees. This locks it into the base.
A properly applied bungee cord would probably keep it from coming "untwisted" during travel. However, I opted to be a little more careful. If you look closely at the second pic, you will notice a tiny brass threaded insert in the bottom of the CO. It's at the extreme right edge of the picture and can barely be seen.
I ran a bolt into that threaded insert (from the top, under the dome) and into an existing hole in the baseplate that just happened to align perfectly. This bolt acts as a stud to keep the CO from untwisting itself. The guy I mimicked used the bungee and has never had any trouble, but I feel better with the stud.
Maybe I'll add the bungee too, just for insurance.
