[VHFcontesting] Stacked Squalos?

I would suggest 4 element horizontal yagis pointed in the key direction 
would serve your purpose better.  I have several 4 element yagi arrays on 
the side of my tower plus some omni directional arrays and in almost every 
direction the yagis perform better.  In no case could I hear a signal on the 
omni antenna that I couldn't hear on the yagis.
