```Yes, I meant they are in an equilateral triangle.  Had a brain fart.
Lots of postings on this subject, but nobody has yet answered my original
question.  I'll post it again.

I have 2 stubs, separtated by a 1/4 wave phasing line on my single vertical.
Will these stubs affect the phasing of the verticals.  That was what I was
