Extra exam question E9C05

WhyAn off-center-fed dipole is fed between the center and one end, rather than at the midpoint, to create a similar feed point impedance on multiple bands. Feeding an off-center-fed dipole between the center and one end, rather than at the exact midpoint, is done specifically to land on a feed point impedance that stays similar across several different amateur bands, letting one antenna and feed line combination work reasonably well on multiple bands without a tuner doing all the work, answer A. It isn't primarily about suppressing off-center lobes, isn't what makes it resonate across a wider continuous frequency range, and doesn't specifically reduce common-mode current, that's a separate consideration usually addressed with a choke.
