I was looking back through some older posts on this thread while killing time on a conference call and saw D15 was listed as being destined for 97W. Is there still a chance for that? That would obviously require a new LNB, but presumably could use the existing Slimline dish.
There was a link to a patent someone dug up back on page 9 for a LNB that had feedhorns designed to receive 17.3 - 20.2 GHz (i.e. specifically including RDBS frequencies) that included a frequency selective reflecting surface on the LNB arm. This would reflect a Ku signal and pass a Ka signal after it reflected off the dish towards the 101 feedhorn, so both could be received from 101 at the same time. If they went this way the LNB arm would need to be replaced as well. Is it designed to be removable on a Slimline dish? Of course, just because there's a patent filed doesn't mean it'll go anywhere, of course. I wonder how that high tech surface would do in places that get snow/ice. Or bird poop
The other thing I was wondering about was there was some discussion about maybe needing more than 4 coaxes at some point, and going to 6. It looks like right now the only open space is 1650 - 2150 MHz on the 99/101 lines, which is where D14's Ka capacity would presumably go, creating a 99cb. But that's all there is, so either they go higher in frequency like VOS suggests, or need another pair of coaxes.
Going to higher frequencies is obviously preferable, assuming that the tuners in legacy capable receivers and SWM 8/16/32 switches can handle the 2350 - 2850 MHz range. If they were forced to go to 6 coaxes, I wonder if there would be any chance of using the flex ports to avoid the need to replace all those SWM multiswitches? They'd have to replicate 95's content on one of the new sats to allow freeing up on both flex ports, but 95 has only 9 transponders, so that would not be difficult.
