A beverage works because the difference in velocity factors (between air and wire? between wire and ground?) bends the wavefront. Does a slinky, with a lower velocity factor, bend the wavefront more? Does it somehow end up with a lower takeoff angle, and maybe better azimuthal directivity than a similar length of straight wire? I am somewhat checked out from work right now, or I would model this in NEC. Right now I'm hoping someone else already has :) Also, do you need special slinkies for constructing a beverage? Say, stainless steel or bronze ones? -- All rights reversed. _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
