After all of the calculations here is a drawing I made for the spacing of a A3S
and A3WS. Hope this helps.
Any other comments welcomed.
Thanks,

Subject: [TowerTalk] Stacking antennas Question
I have an A3S Tribander on my tower and I want to add the A3WS 12/17 meter yagi
above it. I have 7 ft of available mast above the A3S.
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.
