You can make most dipole antennas, including inverted Vs and other configurations, into reversable yagis by adding a relay. Way #1 is to make the director switchable between a director and reflector by adding a relay that shortens or lengthens the resonance of the parasitic element. Way #2 is to swap between driven elements, isolating the twin, so that the other element is parasitic.
