@Syed Not that you need the higher gain to receive the signal, but to narrow down the receive beamwidth? The satellites seem to be about 2° apart. Obviously, some antenna gain would help narrow the beamwidth down some.
So how narrow of a beamwidth at -3db do you need in order for the neighboring satellites not to interfere with the signal you want to receive?

I definitely don’t see lots of scenarios where more than 50 or 100 feet of coax is really required.
