Which of the following is NOT a feature of mitigation bonds?

Mitigation bonds are primarily used in cathodic protection systems to address issues related to corrosion and other electrical interference challenges, especially concerning metallic structures like pipelines. The characteristic that is not a feature of mitigation bonds is enhancing radio communication.

Mitigation bonds work by establishing a low-resistance electrical connection between the structure and the grounding system, thus providing a pathway for stray currents. They also help in decreasing stray voltage, which can be harmful to both the structures and the surrounding environment. Furthermore, one of their core functions is to protect pipelines and other metallic infrastructure from corrosion by ensuring that stray currents do not adversely affect their integrity.

Enhancing radio communication is not a function of mitigation bonds. While electrical interference from stray currents can affect radio signals, the primary purpose of mitigation bonds is not to improve communication systems, but rather to protect structures from corrosion and electrical interference issues. Therefore, the notion that mitigation bonds enhance radio communication does not align with their intended protective and preventive applications.
