← ScienceWhich risk increases when a radio transmitter's power exceeds antenna design limits?
A)Excessive signal phase shift
B)Antenna impedance mismatch occurs
C)Standing wave ratio increases✓
D)Transmitter frequency bandwidth narrows
💡 Explanation
A high SWR results because excessive power causes impedance changes, leading to signal reflection (Standing wave ratio). These reflected waves increase, therefore damage is more likely, rather than simple bandwidth changes or phase shifts within the antenna hardware.
