Experyment with antenna earth elektrode about 600m long

Successful experiment with earth dipole about 150m long encouraged me to experiment with a longer antenna about 600m long. I used industrial earthing on one side and steel beam with ‘C’ cross section immersed in the water on the shore of a small lake served as the other electrode. I used industrial earthing on one side. The antenna consisted of two wires about 150m (symmetric cable) and 600m (PKL) long,

The resistance of the antenna for DC was about 1kΩ.
