What is a common issue with older coaxial cables?

The common issue with older coaxial cables is that they have higher signal loss. This occurs due to several factors, including the type of insulation, the quality of the conductor, and the aging of the materials used in the cable. Over time, the dielectric materials can degrade, leading to decreased performance and increased attenuation, meaning that the signal loses strength as it travels over the cable. This higher signal loss is particularly problematic in applications where maintaining signal integrity is crucial, such as in internet and cable television service.

While older coaxial cables may be less flexible due to their construction and materials, this characteristic does not significantly impact signal transmission. Durability can vary, but many modern cables are designed to be more resilient. Installation ease can also depend on the specific design and context, rather than being a definitive trait of older coaxial cables. Thus, the higher signal loss associated with older coaxial cables is a critical concern that directly affects their effectiveness in data transmission.
