This may be the article that Pete is referring to...

But... I believe that this only works for a single band so you would have to
switch in different delay lines.

This is probably obvious to most, but how would you do a simple combiner
to test stacking dissimilar antennas before investing in a Stackmatch or
similar?

I think you'll be wasting your time with the Stackmatch, unless you
adjust the feedline lengths to compensate for the different positions of
the driven elements relative to your target directions. WX0B wrote a
little article about doing this - probably somewhere on the AS web site.

Yes Doug, I am sure I was on the Force...after my “oops” on Saturday
morning....I checked—twice. When you home the Steppir elements, there is
NO signal, not even noise—hihi.
Ian, I think you have the best explanation—some kind of coupling...I
forgot to add, when I selected the Force it was at 045, the Steppir on
the roof was at 010...so they were “close” to the same direction.
After this development, I am putting the Steppir on top at 67 ft, and
the Force 35 ft below and actually couple them with an Array Solutions
stack match and see how that develops...while working on getting a big
tower, or Bertha up with stacked Steppers at 150 and 75.
