OCF dipoles are obviously a compromise. As a multiband antenna it
better not outperform a specific band dipole.

That's a general statement, but for a correctly fed OCF, your
statement is generally false.

If an OCF is shorter than 1/2 wave for the frequency of operation, it
will not perform as well as the 1/2 wave dipole. However, as the
length of the OCF increases over the 1/2 wave, it generates lobes of
gain in various directions. How many lobes and to where they point
changes according to the relative length to the band, but there is
actually gain.

You can find more information in the ARRL Antenna book or by modeling
the antenna on one of the antenna model ling programs.
