Iím looking forward to your results. I expect the HDB8X factory combiner is attempting to match 37.5 ohms (two paralleled 75 ohm inputs) to a 75 ohm output.

Do you recall if all the reflector tube lengths were the same or are the tubes longer where they extend into the wider centers of the end caps?

Can you tell us the brand & part number of the lower loss combiner you used for your tests? Not the one that came with the antenna.
