← ScienceWhich outcome occurs when a radio frequency (RF) antenna exceeds its maximum power rating?
A)Corona discharge arcs across elements✓
B)Increased far-field signal attenuation
C)Decreased carrier wave frequency
D)Improved impedance matching bandwidth
💡 Explanation
Corona discharge occurs because exceeding the power rating causes the electric field strength around antenna elements to surpass the breakdown voltage of air. Therefore, ionization leads to observable arcs, rather than increased efficiency because those are prevented by design.
