Which outcome occurs when a multi-element Yagi-Uda antenna's driven element is poorly impedance matched?

A)Reduced forward power gain
B)Increased side lobe radiation
C)Enhanced front-to-back ratio
D)Improved bandwidth characteristics

💡 Explanation

Reduced forward power gain results under impedance mismatch because of increased signal reflection back towards the transmitter; therefore, less power radiates forward, rather than improving the antenna beam's characteristics.
