[WriteLog] SO2R contesting question

[AD6E@aol.com]

Jim (et all);

Not to belabor a point, but I thought a quickie expansion of vertical problem 
might help: Ground losses are not just 1/4 wavelength from the antenna. Good 
radials take care of that. As the signal radiates from the vertical the 
electric field, being vertical, induces eddie currents in the earth for many 
many wavelengths until the signal becomes a "sky wave". All those eddies sap 
signal strength both comming and going. Thats why salt water works so well. 
However, it needs several miles of salt water in the desired direction to be 
really effective for DX.

73, Al
