A center-fed dipole with the ends folded down 90 degrees at the midpoint of each side
A half-wave dipole with an additional parallel wire connecting its two ends✓پاسخ درست
A dipole configured to provide forward gain
توضیح
A folded dipole is a half-wave dipole with a second wire running parallel to it and joined to both ends, forming a long narrow loop fed at the center of one conductor. The loop does not add gain; it raises feed point impedance and broadens the usable bandwidth.
