When Inmarsat-B and Inmarsat-C terminals are compared:
Inmarsat-B antennas are larger, but omni-directional, while Inmarsat-C antennas are smaller and parabolic, for aiming at the satellite.
Inmarsat-B 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-B antennas are parabolic for lower gain.
Correct Answer
Inmarsat-B 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.
When Inmarsat-B and Inmarsat-C terminals are compared:
Inmarsat-B units provide greater communications capabilities, with the benefits of greater size, weight, installation expense and initial cost.
Inmarsat-C provides lesser communications capabilities, with the trade-offs of greater size, weight, installation expense and initial cost.
Correct Answer
Inmarsat-B units provide greater communications capabilities, with the trade-offs of greater size, weight, installation expense and initial cost.
Inmarsat-C units are of smaller size, weight, installation expense and initial cost and provide greater communications capabilities due to modern technology.
