How does the attenuation of coaxial cable change with increasing frequency?

As the frequency of an RF signal increases, the alternating current tends to flow closer to the outer surface of the conductor. This phenomenon, known as the skin effect, reduces the effective cross-sectional area of the wire, thereby increasing its resistance and causing more signal loss. Additionally, the dielectric materials used to insulate the center conductor from the shield absorb more energy at higher frequencies. These combined resistive and dielectric losses mean that the overall attenuation of a coaxial cable always increases as the operating frequency rises. Distractors suggesting attenuation decreases or remains independent of frequency ignore these fundamental physical properties. Options mentioning 'Marconi’s Law' are entirely fabricated.
