Re: First satellites launched for global internet from space.
Another forum member has told me this:
Start
Satellites for TV are in geosynchronous orbit, 22000 miles up. The suggested internet ones are zipping around about 750 miles up, so you don't need a dish. Indeed you wouldn't want one, it would be constantly zipping back & forth trying to track these satellites. A simple crossed-dipole aerial would probably work, although I think they plan to use a flat plate phased-array antenna of around 30cm x 20cm. The technology is more like satellite telephone than satellite TV.
End
So, it looks like people won't need a dish at all.
