I don't see much Ku for NSS-5 on Lyngsat. The ones shown are on a spot beam.
We (Bonneville) uplink
C-Band to NSS-5 from Salt Lake, using a 5-meter dish, though. I remember TARBS downlinking their DBS service from some bird near Australia (years ago) at a California location. They needed a 10-15 m dish to do it, since they were spot beams.
