I have a KLM 22C, KLM 40CX, Meyers 2.4 G dish, and Directive Systems 55 el 
1269 loop yagi spaced on 12 feet of cross boom. No noticeable interaction, 
but I'm using high end preamps with good third order intercept and helical 
filtering. In practice, try to space as far as you can.....

A great place to read up on yagi stacking and the concepts of capture area 
etc. is at Ian, G3SEK's site:


Check out the rest of his site. http://www.ifwtech.com/g3sek/ Good Info! I 
highly recommend the VHF/UHF DX book.
