I messed with a few of those some years ago. They seem to have a lousy really high noise figure. Only thing going for them, is with the C-120 flange they are easy to bolt up to a Primestar feedhorn.

Some businesses use the 121 as a private Sat feed. Movie theaters, for example us the 121 to live feed special events, like sporting events, live broadcasts of stage performances ,etc

One thing about those LNBs: They are not great quality. They suffer from frequency drift with age as much as 4~5MHZ. Use a blind scan to compensate. Or if you have a good meter like my AI TurboS2 and can measure the drift and recalculate your frequencies.
