I think rhombics were sometimes chosen for receiving, because they are a
type of wave antenna like the Beverage but with a sharper pattern. But how
the two compare, I can't say.
Rhombics, because of the many small lobes, have poor directivity. As such,
they are not exceptionally good receiving antennas.
As Rudy pointed out:
"People tend to forget that rhombics were originally used for point-to-point
communications with fixed azimuths and distances. While the gain was nice
the real utility was the broadband character of the antennas, especially
when terminated. This allowed the transmit/receive frequencies to be
quickly changed as propagation along a given path varied."
Log periodics relaced them for bandwidth (with similar or slightly less
gain), and curtains replaced them for increased gain (with loss of SWR
bandwidth).
