Why is it crucial to use a calibrated torque wrench when tightening antenna connections, even if they 'feel' tight enough?

It is crucial to use a calibrated torque wrench when tightening antenna connections, even if they 'feel' tight enough, because proper torque is essential for ensuring a reliable electrical connection and preventing damage to the connectors. Applying too little torque can result in a loose connection, leading to signal loss, intermittent performance, and potential arcing or overheating. Applying too much torque can strip the threads, crush the connector, or damage the internal components, also leading to signal degradation or failure. A calibrated torque wrench ensures that the connection is tightened to the manufacturer's specified torque value, which is the optimal balance between ensuring a secure connection and preventing damage. 'Feeling' tight is subjective and does not guarantee that the correct torque has been applied. Furthermore, using a calibrated torque wrench provides a documented record of proper installation, which is important for warranty purposes and troubleshooting future issues.
