Not a lot! http://www.satelliteguys.us/free-air-fta-discussion/39119-40-c-ku-band-dish.html
Its a fun project, but thats it!

Pete (PSB) is always a good source of information. I don't spend a lot of time on the forums (because I don't have a lot of free time). My normal day in the office is 14 hours long, and that's six days a week. | Well fellas....any update on this new product

No prob. I'm guessing its for marine use or its from europe
Either way, I'll wait for the offical announcement

Sorry, I was meaning the shipment of BSC621-2 with 10750 L.O. is on a ship making its way to the USA.
No info on the other projects, but I have a few ideas  |

I'd recieved a BSC 621 from Sadoun, great folks there. Just yesterday I'd mounted the unit on a 10' dish I'd salvaged. The C band portion of the unit has been operating very well, some signals have gone up 25-50% more, switching from a 5' to a 10' dish. The C band portion of this unit seems to operate as well as a ASC 421. The Vertical portion of the Ku side was returning signals as high as 90% on G10R. I've been having some trouble receiving the Ku Horizontal signals. The tech rep. with Sadoun has been away, so I called DMS International and they suggested I check the scew and dish pointing. The scew and dish pointing are fine. I've spent a half day today trying a number of adjustments with the unit. The Ku side is recieving Vertical signals, listed at Lyngsat, as Vertical, while the C band side is recieving Vertical signals , listed at Lyngsat as Horizontal. I feel that the Ku LNBF is 90 deg. out of rotation from the C band LNBF. Its a nice unit, but I'm puzzled by the problem with the Horz. signal with the Ku LNBF. We've discussed issues combining Ku and C band wave guides, not an easy matter.

The wave length difference between C and Ku makes for some interesting observations. Ku here is 11.7~12.2GHz while C is 3.7~4.2GHz. The difference in frequency translates to a Ku wave guide that is one third the size of a C wave guide because of the wave length. If your dish has large holes the shorter Ku frequency might bleed through the dish and be reflected very little. Holes in the dish should be no larger than the lead of a lead pencil. Also, because Ku is 1/3 the size (in wave length), your dish alignment and polarity alignment must be 3 times as accurate as C band. Higher frequencies have greater loss. Coax and connectors all play a big part in loss along with any other devices you may have in line. Ku reception that suffers on C band dish can be tracked back to one or a combination of these and other factors. Also, keep in mind that older C band dishes were never designed for Ku. Therefore, the manufactures had no reason to make the surface accuracy of dish good enough for Ku. There are other factors that play into it but these are the most important ones.
