What are the directional characteristics of the INMARSAT-C SES antenna?

The directional characteristic of the INMARSAT-C SES antenna is marked by a very narrow beam width that focuses directly upward. This feature is significant as it allows the antenna to establish a strong and precise communication link with satellites that are positioned in geostationary orbit above. Such narrow beam widths help in minimizing interference and maximizing signal quality, ensuring that data transmissions are reliable and effective over longer distances.

This highly directional nature is essential for satellite communication systems where precise alignment with the satellite is necessary for optimal performance. In contrast, options referring to wide beam coverage or omnidirectional coverage imply a broader signal dispersal, which is not characteristic of the INMARSAT-C system, as it’s designed to facilitate focused communication with satellite networks rather than widespread signal distribution.
