Which risk increases when a microwave antenna corrodes?

A)Reflected power at feedpoint rises
B)Bandwidth of radiated signal decreases
C)Antenna gain characteristics improve
D)Polarization becomes increasingly circular

💡 Explanation

Antenna corrosion increases surface resistance, causing impedance mismatch because the **skin effect** dictates conductivity concentrates in the outer layers; therefore, more power reflects back, rather than radiating efficiently, and bandwidth characteristics are unaffected.
