Why should the outer jacket of coaxial cable be resistant to ultraviolet light?

The outer jacket of coaxial cable needs to be resistant to ultraviolet (UV) light because UV radiation can cause significant damage over time. When a coaxial cable is exposed to sunlight, the UV light can degrade the materials in the jacket, leading to cracking, brittleness, and ultimately, failure of the jacket. If the jacket is compromised, it can allow moisture and water to enter the cable, which can severely affect the performance of the cable, increase the potential for shorts, and cause signal loss. Therefore, having a UV-resistant jacket is critical for maintaining the integrity of the coaxial cable and ensuring reliable operation, especially when installed outdoors.
