What is the primary function of a tensioning anchor in a high line setup?

The primary function of a tensioning anchor in a high line setup is to manage the tensioning system. This involves maintaining the necessary tension in the rope to ensure that the system operates effectively and safely. By properly managing tension, the tensioning anchor helps prevent slack in the line, reduces the risk of dynamic loads, and ensures that the setup remains stable during operations.

This stability is crucial for the safety of both the rescue team and any loads being transported along the high line. Other options may touch upon various aspects of a high line system, but they do not accurately capture the essential role of the tensioning anchor in ensuring proper function and safety during rescue operations.
