← ScienceWhich risk increases when mismatched impedance causes standing waves in a high-power RF transmission line?
A)Component overheating due resonance effects✓
B)Decreased antenna radiation efficiency
C)Reduced signal bandwidth allocation
D)Increased signal propagation velocity
💡 Explanation
Component overheating increases due to maximized voltage amplitude through constructive interference via resonance effects along components. This is because a high SWR forces higher currents and reflection; therefore overheating increases rather than decreased antenna efficiency under matched conditions.
