Is there any problem with mounting the 12/17 m yagi at 7 ft above the  
10/15/20 yagi? The boom length on the 12/17 yagi is 14 ft and I have heard  
times that 1/2 boom length is sufficient separation. The antennas are NOT  
harmonically related.
    Electrical spacing is one thing. Even more  important is the mechanical 
spacing. What's your local windspeed rating? What  is the mast material? I 
don't think you want it to bend when a big windstorm  comes up.
