Which risk increases when microwave antennas experience heavy icing?

💡 Explanation

Ice accumulation changes the antenna impedance, increasing signal reflections; this is because of *impedance mismatch*, therefore reflected power rises rather than signal transmission. Decreased gain and encryption factors do not relate to impedance changes caused directly by icing.
