Which outcome occurs when a microwave antenna's radome accumulates heavy, wet snow?

💡 Explanation

Signal attenuation dramatically increases because the **dielectric loading** changes antenna impedance, causing a mismatch and diminished radiation efficiency. Therefore, signal strength drops due to absorption rather than bandwidth alteration, beam sharpening, or polarization changes that snow geometry wouldn’t specifically cause.
