← ScienceWhich standing wave ratio (SWR) consequence occurs when transmission line impedance mismatches antenna impedance?
A)Increased transmitter power reflected back✓
B)Maximized antenna radiation efficiency results
C)Lowered transmission line characteristic impedance
D)Destructive interference cancels the signal
💡 Explanation
Increased transmitter reflected power results because impedance mismatch causes standing waves. The principle of wave reflection dictates this; therefore the transmitter's output is partly reflected, rather than having all power radiated, which represents perfect matching.
