Hello !

I have a negative experience using a well casing. I have a well drilled about 120m deep (~350feet). The pump is hanging about 65m down in a steel wire. From the earth surface and down about 20feet there is a steel tube about 5 inches in diameter. The whole thing was connected to the radials in order to improve the antenna current. However there were absolutely no change in current when connecting. The well here is about 65feet from teh feedpoint. But give it a try. Hopefully you are luckier than I HI. The soil here is "solid" clay about 7feet deep.
