Which risk increases with mismatched impedance in coaxial cable transmitting high-frequency signals?

💡 Explanation

When impedance is mismatched in coaxial cable, signal reflection occurs because the energy transfer is not optimized and creates interference patterns, leading to increased standing waves that amplify voltage fluctuations. Therefore, reflection and standing waves increase, rather than dielectric breakdown, radiation leakage, or capacitive distortion, which require distinct material or geometric properties to manifest.
