Yes, but the rhombic or Vee antenna usually needs sides which are
wavelengths long to produce significant gain.

I was responding to your TV antenna example that exhibited the V shape
with parasitics. The long and short wavelengths both point along the
major axis.

I don`t know what Art has proposed.

Nobody does.

The TV antenna on the roof near me looks like a Yagi with its
elements all bent to the same angle with the boom. Their lengths aren`t
multiwavelength even at 200 MHz. Maybe at UHF?

Exactly.

VHF gain would depend on
phasing between the reflector and the driven element, and the multiple
directors and the driven element. Thus its performance would begin with
its similarity with the straight Yagi, I`d wager.

Exactly (but probably not with any spectacular gain for all the
elements).
