Hi Stefan Thanks for your answer! No island ;) 73 LA5VNA Steinar On 29.07.2018 23:53, DK7FC wrote: > 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. > > 73, Stefan > > Am 29.07.2018 23:41, schrieb LA5VNA: >> >> 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. >> >> LA5VNA Steinar >> >> >> >> >> >> >> > > |
