Superbertha Yagis were probably designed by WA3FET,perhaps K3LR was
involved. I would reach out to them. NR5M used some Superbertha Yagis on
his super-station that seems to be inactive lately. Perhaps George has a
manual for that model.
If it was me, I would just model one using your hardware. YU7EF and G0KSC
have some good OWA designs to start with.

A few years ago I acquired two what I am pretty sure are 15MOWA-36 yagi that
were made by W3TX at SuperBertha.com. I have not been able to reach W3TX or
find any information about spacing / element length etc.
I can, of course, make measurements and put what I have into EZNEC and
redesign
these antennas but before I do that I figured I would see if anyone has a
manual or information about these antennas.
There are snapshots of the web site on the WayBackMachine but no info beyond
the above model number.
Thanks
