How is a signal radiated from an Inmarsat-C system's antenna?
It is a highly focused directional signal that must be beamed at the desired satellite.
It is usually radiated in an omni-directional pattern, but an optional feature allows it to be directional for use when the vessel is on the fringe of the satellite's footprint.
Correct Answer
It is radiated in an omni-directional pattern.
It is radiated in an omni-directional pattern that can be reversed by the Operator to attain directional beaming to an alternate satellite.
