When Inmarsat-FBB and Inmarsat-C terminals are compared:

Inmarsat-FBB antennas are larger, but omni-directional, while Inmarsat-C antennas are smaller and parabolic, for aiming at the satellite.

Inmarsat-FBB antennas are parabolic and smaller for higher gain, while Inmarsat-C antennas are larger but omni-directional.

Inmarsat-C antennas are smaller, but omni-directional, while Inmarsat-FBB antennas are parabolic for lower gain.

Inmarsat-FBB antennas are larger, but directional for higher gain, while Inmarsat-C antennas are smaller and non-parabolic, and do not require aiming at the satellite.
