Under ideal conditions twinlead doesn't radiate at all. However, anything that unbalances the line will cause it to radiate, including running it past another conductor in close proximity. Also, I'm not aware of any high-gain omni antenna designs that are balanced except possibly the vertically stacked dipole arrays. But then you'd have to design a corporate feed network out of twinlead too. Yikes!! Bob NO6B
