4.5-4.8 GHz has always been referred to as "Insat C band" as Insat was probably the first satellite operator that openly provided service in this band. I personaly bought a Norsat 8115I back in 2011 and it took more than 3 years when the first picture appeared on the TV screen and believe me or not, $120 was not even the half of the price I paid.

Anyway, 35K (or typical 20K) is nothing for small dishes. I`d like to point out to the fact, that it was the Superior Satellite company that announced this LNB as the first one...and then, because of the cooperation with Norsat, Norsat started offering their Norsat 8000RI.

Later more companies started selling similar product even I think it is the same lnb with different stickers.

Also, there is a reason why Superior Satellites recommends to use this LNB on "bigger" dishes - 3.7m +.
Modified Frequencies C-Band – SSE
Those of us who have some experience with different LNBs know why....
By the way, only fools wait until orbit is full of signals and satellite equipment is as cheap as chips! You have no idea how much fun and joy you miss guys!
Everybody fishes in the same river of Ku band....a small group of people is not afraid to go and fish in the lake of C band...those few of us try their luck in the sea of Ka or Extended C band...but only 3 as far as I know dare to conquir the almighty ocean of X band!
We are there `cause we dare, not because we can afford that!
