[TowerTalk] Stacking antennas Question

[TERRELL90 at comcast.net]

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, 

Terry, NN1L

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.
