Discussion
Why is a folded dipole often used as the driven element of a Yagi?
Answer: D
Coupling drops the driving point resistance to perhaps eighteen ohms, and the folded dipole's factor of four raises that to about seventy, which a four to one balun then converts to fifty. It also widens the bandwidth a little. Its radiation is the same as a plain dipole's, and mechanical strength and pattern width are incidental. Choosing a driven element whose impedance transformation cancels the loading is neater than adding a separate matching network.
