Is the 117G HUB utilized when the main power or main battery is removed or dead?

The 117G HUB (Radio Hub) is designed to maintain operational functionality even when the main power or main battery is removed or dead. This capability is critical in ensuring that communication channels remain open and operational under varying power conditions. The 117G HUB is engineered to support backup power systems that can take over seamlessly when the primary power source fails. This feature is particularly important in military operations where maintaining communication can be vital for coordination and effectiveness.

In this context, other options suggest limitations or conditions under which the HUB operates that do not accurately reflect its purpose or capabilities. For instance, stating it is only used during maintenance or only if damaged would imply that it is not a reliable backup system for power-related issues, which contradicts the design intent of ensuring continued functionality regardless of the main power state.
