[amsat-bb] LNB use on 10 Ghz?

Hello,Questions about the discussion on inexpensive downlink using the satellite TV LNB's. Do they require any conversion to get from 11 Ghz down to the 10ghz ham band? If they don't, is there any significant loss in signal from being used on a different frequency than they were intended for? Is there anything posted on a Web page showing a working setup? Lastly, (I promise) Are there any working sats in the 10ghz range to test a system on?
