>
> I'm working on a tower project and it's nearing completion. One of the
> items I'm looking into is putting up four different yagis on four
> different bands on the tower:
>
> (From the top of the mast, down)
> M2 432-13WLA on 70cm
> Cushcraft 13B2 on 2m
> Cushcraft A50-5S on 6m
> Mosely CL-33 tribander on HF
>
>
> How much vertical separation do I need between each antenna on the stack
> in order to avoid unwanted interaction?
