Is it a fair assumption that dissimilar yagis (e.g., Ed's 15m Telrex and M2)
can be phased (e.g., in a vertical 2-stack) by mounting the yagis so their
driven elements are vertically aligned?  I have an impression that it isn't
necessarily so - that the apparent phase center, if you will, for a yagi is
influenced by the coupling between the DE and other yagi elements.  Thus,
for example, a point 10 wavelengths out horizontally from a yagi's DE won't
necessarily be in phase with the DE feed point.
