Why might aerial installations be more challenging than underground installations?

Aerial installations can indeed face more environmental factors affecting performance compared to underground installations. This situation arises for several reasons.

Firstly, aerial installations are often exposed to elements such as wind, rain, snow, and extreme temperatures that can impact the integrity and performance of the equipment. For instance, high winds can lead to sway or movement of cables and infrastructure, which can compromise connections and stability. Additionally, rain or snow can introduce moisture into the system, leading to corrosion or other forms of damage that are less prevalent in underground installations where the environment is more stable and protected from direct weather exposure.

Furthermore, aerial lines may also be subject to interference from nearby trees, buildings, or wildlife, which can physically damage the installations or cause signal interference. The combination of these factors means that aerial installations require more careful planning and monitoring to ensure they function effectively over time.

In contrast, underground installations, while they may have their own set of challenges, typically enjoy protection from environmental stresses, making them generally less susceptible to the immediate effects of weather and other external environmental factors. This distinction is what makes the first response the correct one regarding the challenges faced when dealing with aerial installations.
