You mean something like this?
If so, get the version without the -2 on the end - it's standard Ku, and this one is Universal (I assume that'd be what you would want).
I'm sure you can find much discussion of this and similar units on the forum - maybe even a review.
I'm experimenting with one here in Holland.
It's a BSC 621-2 with conical feed mounted on an 4 inch offset dish.
But I have to start all over again since a storm damaged my polemountings completely.
I've got two C/Ku corotors with LNBs that came off dishes I rescued. I haven't tested the LNBs or the servos in the recent past, but anyone who wants them can have them for the shipping cost.
