Which behavior arises when a transmission line's shunt capacitance significantly increases due to moisture ingress?

💡 Explanation

When shunt capacitance increases, the increased capacitive reactance provides a low impedance path that shunts high-frequency signals across parallel conductors, because the effect of capacitive reactance becomes more prominent at higher frequencies, leading to increased signal attenuation with rising frequency.. Therefore attenuation increases as frequency rises, rather than impedance becoming inductive, velocity increasing, or reflections diminishing which depend on different signal perturbations.
