"I`d like some advice on building the phasing harness required for the
following antenna,"

The antenna described has one-wavelength spacing between antenna
elements. As velocity in the coax is only about 2/3 that in free space,
one-wavelength of phase delay in cable won`t stretch between the antenna
bays as shown. Solution is to add another wavelength of phase shift to
the interconnection cable or to simply use a pair of identical cables of
almost any length to parallel the bays at a driving point. Any desired
phase delay can be added to one or the other of the cables to shape the
pattern.
