Although the term "efficiency" seems to be used with gay abandon in
this place, the rhombic is not close to 100% efficient, a portion of
the transmitter power (approaching 50%) is dissipated in a
non-radiating loss.

That loss does not have an adverse impact on the gain in the desired
direction, and so it should not be regarded as a disadvantage of
itself.
