I have to disagree, for two reasons:

1. An inverted vee has a vertical component of radiation, and man-made
noise is predominantly vertically polarized, so an inverted vee will
pick up more man-made noise than a dipole.

2. An inverted vee with an apex angle of about 90 degrees is almost
perfectly omnidirectional in the azimuth plane, whereas a dipole is
quite directional, having sharp nulls off the ends. If you are lucky
enough to have the dipole's end pointed toward a noise source, the
dipole will be quieter than the vee.
