Too bad that the Ka band cannot be excluded, though. That would be a nice improvement of that site.
For he rest I agree fully with you, that is exactly how I do it as well, since I'm only interested in Ku-band. The good thing using that site is that you can also filter out any satellite positions you cannot see with your dish, keeping the size of the file down.
However I was answering a question about the splitting of bands on a satellite by adding a position 1 tenth of a degree away to split the bands on the satellite, and possible reasons to do that. If someone has both a C-band LNB/dish and a Ku-band LNB/dish, I think he would need to have two separate satellites to be able to handle both bands. And that is exactly what can be done by having that split.
@Robinson
You asked for reasons to make such splits, amd I simply mentioned some. I agree with you that there will not be many people combining several bands in their installations.
