I proved this for myself. I took numerous measurements at many compass points comparing an antenna half-wave-spaced from the tower vs. a top mounted omni on the same tower. There was a very definite north-south gain increase vs. east for the half-wave-spaced antenna. In general terms, the side-mounted antenna was 4db worse than the top-mounted omni to the north, and 11db worse than the top antenna to the east. Again, the result of dozens of measurements in the field. Does that make sense? Laryn K8TVZ
