Which aspect degrades antenna signal when rain accumulates?

💡 Explanation

Absorption from water results in signal attenuation because electromagnetic energy is converted to thermal energy via increased molecular dipole interaction, causing energy loss during wave propagation; therefore attenuation increases; rather than refraction shifts or impedance mismatch with the transmission line.
