However, about 150 feet from my house is a water well in the form of an 8 inch diameter steel pipe that goes down 275 feet! Has anyone on the list had any experience using such as a ground for a Marconi antenna? ----------------------------------------------------------- In my experience the performance of different existing grounds for LF is hard to predict. The only thing is to try it. Note the differences in antenna current as you connect different grounds. Peter G3LDO
