No. The HPBW is explicitly stated as 43° which is it's calculated value at the low end of UHF, it narrows to almost 30° at 698 MHz. Only the major lobe is considered when the HPBW is specified.
Son of a gun! The baluns can be installed out of phase! =(

Is there a way to test the balun prior to installing?

Never mind. I was going to try it but the parts are almost 35 bucks so I ordered a DB4e to try instead.
