What distinguishes preparing QR hardline coaxial cable for installation?

1. The polyethylene jacket is removed first

2. It requires additional connectors

3. The aluminum shield is stripped before removing the jacket

4. It uses a different coring method

The correct answer is: The aluminum shield is stripped before removing the jacket

The correct answer pertains to the specific technique required for handling QR hardline coaxial cable. Stripping the aluminum shield before removing the polyethylene jacket is crucial for the effective installation of the cable. By removing the aluminum shield first, a technician can expose the underlying insulation without damaging it during the jacket removal process. This method minimizes the risk of compromising the integrity of the cable, ensuring that it functions properly once installed. Other methods of preparing different types of cables may not involve stripping the shield first, and could instead start with the jacket, leading to potential issues such as excessive damage or improper termination. Thus, the unique handling requirements of QR hardline coaxial cable, specifically the order of components removed, make this preparation technique essential for ensuring high performance and reliability in the communication infrastructure.
