Default Feeding a 4 bay vertical folded dipole

I need to build a 4 bay folded dipole like the one use on vhf/uhf
repeaters. The folded dipole is easy
enough to figure out but how do you get the 4 - 300ohm dipoles to
combine to one 50ohm feedline,
I have looked close as i can at these and there is no combiner but it
looks like maybe some coax
phasing stubs or lengths of coax inside the antenna support mask?


The ARRL book, FM and Repeaters (1970s) included information on building a
"phasing harness".


IIRC -- without running down to the ham shack and diggng through my old
copies -- some ARRL Handbook (and/or Antenna Handbook) editions back
then had a complete project description for the whole shee-bang: folded
dipoles, matching/phasing harness, mounting technique(s), etc.
