If that were true, the low-angle radiation would not move up to create a lobe centered on a "takeoff angle." But in any case, the graphic linked below (Terman) does not show a lack of radiation from a monopole at elevation angles between 1 and 5 degrees. http://i62.photobucket.com/albums/h85/rfry-100/TermanFig55.jpg _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
