The TH11DXX that G3TXQ compares to the Hexbeam has at least 3 elements on each band and is a modern design, no traps. If someone found that the C3 (2 el on each band) outperformed it, I would be very suspicious that something was wrong with the sample tested. I did look at the wrong picture and you are correct that the XR5 is 9 elements.
