I agree with Larry, the Directive Systems link has some great information on
spacing of yagi antennas to keep the interaction down. Scroll down about a
fourth of the page and there is a great illustration of what you want to
achieve. If you know the aperture, you can easily calculate the needed space
between the different antennas.

Hi Mark,
The best paper I have seen is HOW TO PLAN THE INSTALLATION OF MULTIPLE VHF
ANTENNAS ON ONE MAST on Directive System's web site:
http://www.directivesystems.com/STACKING.htm. This should be enough to
point you in the right direction.
73,
Larry
