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
many
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.
