← TechnologyWhich risk increases in a cellular communication tower when icing causes substantial antenna deformation?
A)Reduced impedance matching efficiency✓
B)Increased signal reflection coefficient
C)Amplified power dissipation inside circuitry
D)Elevated carrier frequency instability margin
💡 Explanation
Deformation alters the antenna geometry, therefore causing a dramatic impedance mismatch, because the *input impedance* deviates from 50 ohms; rather than efficiently radiating power, more energy is reflected or dissipated due to internal resistances.
