Is a raibeam two driven elements with a phasing harness?

According to an ARRL September, 1997, review of the Raibeam RB-206B (6
meters), it is a two-element HB9CV-type antenna. They go on to say

"In that design, two
dipole elements are driven out of phase
with respect to each other and closely
spaced."

The article footnote says

"For a description of the HB9CV mini-beam,
see the RSGB VHF UHF Manual (4th edition),
G. R. Jessop, G6JP, ed, pp 8.30 and
8.31."
