The most common method of installing aerial cables for telephone and CATV organizations?

• A. Lashing/Overlash
• B. Direct burial
• C. Underground duct
• D. Aerial spooling

Answer: (A)

Lashing or overlash is the common method because it uses a messenger wire stretched between poles and the aerial cables are tied to that messenger at regular intervals. This setup lets multiple cables share one lightweight support, making long spans economical and easy to install and maintain. It reduces pole loading, simplifies future upgrades, and works well for the typical overhead routes used by telephone and CATV networks. Direct burial and underground duct require digging and trenching, which is more expensive and disruptive for aerial paths. Aerial spooling is generally for temporary or specific short-term situations and isn’t the standard approach for the main overhead distribution lines.
