When directly burying coaxial cable, what should be avoided?

1. Excessive winding of the cable

2. Reverse bending of the cable when unreeling

3. Using insufficient depth for burial

4. Unrolling cable in wet conditions

The correct answer is: Reverse bending of the cable when unreeling

When directly burying coaxial cable, avoiding reverse bending of the cable when unreeling is crucial. This is because coaxial cables are designed with specific bend radii that must be adhered to in order to prevent damage. Reverse bending can stress the internal construction of the cable, potentially leading to decreased performance, signal loss, or even permanent damage to the cable's shielding and conductor. Maintaining the manufacturer's specified bend radius ensures the cable functions properly and maintains its durability in the installation. While concerns like excessive winding, burial depth, and wet conditions are also important considerations, they pertain more to installation practices and the overall longevity and performance of the coaxial cable rather than the immediate structural integrity that reverse bending can compromise. Ensuring that the cable is installed properly without reverse bends is vital for its optimal operational lifespan.
