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.
