Power is I^2, so we can assume if we divide current between enough radials each radial will not radiate much at any distance compared to the antenna. We not only have cancellation at a distance, we have much less near each radial. Spreading things around is a good thing. 73 Tom _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
