Could an island be used as a slot radiator?   
Feed either side of the island.

Hello Steinar,

Placing two electrodes into sea-water will give a low resistance but no radiation resistance, so the efficiency will be poor.
Maybe you own one of the nice islands up there in Norway? A stony mountain sourrounded by sea water and then a loop from the sea to the top of the mountain and then back to the sea. That would be ideal.

Hi all , long time

I'm thinking of doing an experiment with an "earth antenna" in sea water. I have a cabin located just 15m from the sea. What effect will sea water have, if I place two electrodes ca 250 meters apart from each other in the sea outside the cabin?

The frequency I will use is 8KHz.
