Try a Winegard 5-foot mesh, I sold two of them as a fixed dish, EL, but it had the ability to be able to use a motor, I used it on C-band for RTPI I do recall the mesh size being small, and good for KU, and it worked almost as well as there 6 foot one did, it was a deeper dish, so that offset the small size to work as well, also being deeper if I'm correct, but maybe not, it gives you more rejection from the side loop of a bird 2 degrees away, which is always the huge issue for small C-band dishes
