In aerial installations, what do cable manufacturers recommend forming in hardline coaxial cables?

1. Joint splices for better connectivity

2. Expansion loops to allow cable movement

3. Coiled wraps to prevent cable damage

4. Fiber optic splices to enhance performance

The correct answer is: Expansion loops to allow cable movement

In aerial installations, cable manufacturers recommend forming expansion loops in hardline coaxial cables to accommodate movement caused by temperature changes, wind, and other environmental factors. Expansion loops allow the cable to expand and contract without putting excessive strain on the connections or causing potential damage to the cable itself. This flexibility is essential in aerial applications where cables are exposed to varying conditions, helping to maintain the integrity and performance of the installation over time. The other options do not align with the specific needs of aerial installations. Joint splices, while useful for connectivity, do not address the movement issues inherent in aerial settings. Coiled wraps may protect cables but are not typically recommended as a primary method for handling cable expansion or contraction. Fiber optic splices are unrelated to coaxial cables as they pertain to a different type of cabling altogether.
