Eric Scace, K3NA, presented a paper at Dayton on a stack of
XA's. It was probably around 1992 or so. It's worth digging
up, or contacting him directly for info.
I would not be surprised to see slight advantages of the
monobanders, but anything more than that, if not explainable
by height/stacking differences in models, would amaze me.
Unless something's broken.
W4XS's comments regarding polarity are probably worth looking
into...although the notion of climbing to check is unappealing.
W2UP's comments regarding the XA's mechanical complexity are worth heeding,
if you don't already know about it.
Color me..."rebuilt 4 XA's, with all possible colored end caps, and have
achieved my lifetime quota"!
