How are they supposed to provide full coverage for the US, with a limited constellation, from LEO? I get that the huge antenna would help them get a MUCH larger angle than starlink does, but basic orbital mechanics seems to make this impossible.

My guess is that they would have to be placed in higher orbits than Starlink, perhaps more akin to the Iridium constellation.
