The northeast end of my 30 degree/210 degree two-wire Beverage terminates about 20 feet (horizontal distance) from the 7200 volt (line to neutral) line that runs along the road at the north end of my property. It works great. So far, I've never noticed any "coupling" (because of proximity) between the Beverages (I have 12 of them - 6 2-wire runs) and any other antenna or metallic object. When there is power line noise, then nearly all of the Beverages hear it, in varying degrees, depending greatly on how close the source is. When the source is very close, almost all of the Beverages hear the noise, and there isn't any discernible difference with regard to the normally preferred direction. When the source is a mile or more away, then the Beverages seem to exhibit their normal directivity. Note that none of my Beverages run parallel to any power lines, except the 90 degree/270 degree Beverage, which is about 500 feet from the power lines.
