Which radio is a man-pack portable radio used for long-range, single-channel UHF satellite communication?

The choice of the AN/PSC-5D as a man-pack portable radio designed for long-range, single-channel UHF satellite communication is accurate due to its specific capabilities. The AN/PSC-5D is known for its ability to facilitate communications over satellite systems, particularly in challenging environments, making it suitable for military and tactical use. Its design incorporates features for single-channel communication, allowing it to maintain reliable links over extended distances via satellite.

This radio operates in the UHF range and is engineered for portability, making it suitable for troops on the move who require robust communication solutions in various operational scenarios. The inclusion of advanced encryption and secure communications also strengthens its utility in military applications.

While other options may feature various communication capabilities, they do not specifically emphasize long-range UHF satellite communication in the same manner as the AN/PSC-5D.
