  • Coaxial Cable Attenuation by Type

    Selecting the proper coaxial cable is an important part of building an efficient amateur radio station. Different cable types exhibit different amounts of signal loss, known as attenuation, which increases as frequency rises. The chart below compares several common coaxial cable types and their approximate signal loss in decibels (dB) per 100 feet at various…
