Hi Howard!
Thwe optimum spacing of a pair of stacked Yagis depends on what you are
trying to achieve...

Many popular stacked Yagi designs place the lower antenna at half the
height of the upper antenna.  A little modelling shows the advantage of
this choice.  I use one wavelength spacing on 10M (35/70 ft) and 15M
(48/96 ft), but the high angle radiation of a closer spaced stacked Yagis 
is more desirable on 20M (50/100 ft) on the East Coast to Europe path.

73!
