Curious if you had any problems ordering them, and if I may ask, what did
they run you?

So you started with a DB224E, but installed a DB224A harness on it? Or was
this a DB224A to begin with?
Altering the vertical spacing (within reason) will likely have little effect
on the VSWR.

I saw the same thing on a recent DB404 UHF dipole array from Andrew. I
didn't see the open stub until I was already at the site with the tower crew
so I didn't get a chance to dissect/analyze it further.

Without knowing its specific function, it's hard to say what effect extend
the length would have.
