← TechnologyWhich risk increases when microwave antennas experience heavy icing?
A)Reflected signal power increase✓
B)Reduced amplifier gain stability
C)Increased data encryption overhead
D)Harmonic frequency generation ceases
💡 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.
